I am trying to launch chrome with an URL, the browser launches and it does nothing after that.
I am seeing the below error after 1 minute:
Unable to open browser with url: 'https://www.google.com' (Root cause: org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
(Driver info: chromedriver=2.39.562718 (9a2698cba08cf5a471a29d30c8b3e12becabb0e9),platform=Windows NT 10.0.15063 x86_64) (WARNING: The server did not provide any stacktrace information)
My configuration:
Chrome : 66
ChromeBrowser : 2.39.56
P.S everything works fine in Firefox
Thumb rule
A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing --no-sandbox flag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.
This error message...
org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Your code trials and the versioning information of all the binaries would have given us some hint about what's going wrong.
However as per Add --disable-dev-shm-usage to default launch flags seems adding the argument --disable-dev-shm-usage will temporary solve the issue.
If you desire to initiate/span a new Chrome Browser session you can use the following solution:
System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized"); // open Browser in maximized mode
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
WebDriver driver = new ChromeDriver(options);
driver.get("https://google.com");
disable-dev-shm-usage
As per base_switches.cc disable-dev-shm-usage seems to be valid only on Linux OS:
#if defined(OS_LINUX) && !defined(OS_CHROMEOS)
// The /dev/shm partition is too small in certain VM environments, causing
// Chrome to fail or crash (see http://crbug.com/715363). Use this flag to
// work-around this issue (a temporary directory will always be used to create
// anonymous shared memory files).
const char kDisableDevShmUsage[] = "disable-dev-shm-usage";
#endif
In the discussion Add an option to use /tmp instead of /dev/shm David mentions:
I think it would depend on how are /dev/shm and /tmp mounted.
If they are both mounted as tmpfs I'm assuming there won't be any difference.
if for some reason /tmp is not mapped as tmpfs (and I think is mapped as tmpfs by default by systemd), chrome shared memory management always maps files into memory when creating an anonymous shared files, so even in that case shouldn't be much difference. I guess you could force telemetry tests with the flag enabled and see how it goes.
As for why not use by default, it was a pushed back by the shared memory team, I guess it makes sense it should be useing /dev/shm for shared memory by default.
Ultimately all this should be moving to use memfd_create, but I don't think that's going to happen any time soon, since it will require refactoring Chrome memory management significantly.

Outro
Here is the link to the Sandbox story.
I started seeing this problem on Monday 2018-06-04. Our tests run each weekday. It appears that the only thing that changed was the google-chrome version (which had been updated to current) JVM and Selenium were recent versions on Linux box ( Java 1.8.0_151, selenium 3.12.0, google-chrome 67.0.3396.62, and xvfb-run).
Specifically adding the arguments "--no-sandbox" and "--disable-dev-shm-usage" stopped the error.
I'll look into these issues to find more info about the effect, and other questions as in what triggered google-chrome to update.
ChromeOptions options = new ChromeOptions();
...
options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");
We were having the same issues on our jenkins slaves (linux machine) and tried all the options above.
The only thing helped is setting the argument
chrome_options.add_argument('--headless')
But when we investigated further, noticed that XVFB screen doesn't started property and thats causing this error. After we fix XVFB screen, it resolved the issue.
I had the same problem in python. The above helped. Here is what I used in python -
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('/path/to/your_chrome_driver_dir/chromedriver',chrome_options=chrome_options)
I was facing the same issue recently and after some trial and error it worked for me as well.
MUST BE ON TOP:
options.addArguments("--no-sandbox"); //has to be the very first option

In my case in the following environment:
Windows 10
Python 3.7.5
Google Chrome version 80 and corresponding ChromeDriver in the path C:\Windows
selenium 3.141.0
I needed to add the arguments --no-sandbox and --remote-debugging-port=9222 to the ChromeOptions object and run the code as administrator user by lunching the Powershell/cmd as administrator.
Here is the related piece of code:
options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument('--disable-infobars')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--no-sandbox')
options.add_argument('--remote-debugging-port=9222')
driver = webdriver.Chrome(options=options)
I ran into this problem on Ubuntu 20 with Python Selenium after first downloading the chromedriver separately and then using sudo apt install chromium-browser Even though they were the same version this kept happening.
My fix was to use the provided chrome driver that came with the repo package located at
/snap/bin/chromium.chromedriver
driver = webdriver.Chrome(chrome_options=options, executable_path='/snap/bin/chromium.chromedriver')
Update:
I am able to get through the issue and now I am able to access the chrome with desired url.
Results of trying the provided solutions:
I tried all the settings as provided above but I was unable to resolve the issue
Explanation regarding the issue:
As per my observation DevToolsActivePort file doesn't exist is caused when chrome is unable to find its reference in scoped_dirXXXXX folder.
Steps taken to solve the issue
I have killed all the chrome processes and chrome driver processes.
Added the below code to invoke the chrome
System.setProperty("webdriver.chrome.driver","pathto\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
driver.get(url);
Using the above steps I was able to resolve the issue.
Thanks for your answers.
In my case it was problem with CI Agent account on ubuntu server, I solved this using custom --user-data-dir
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
My account used by CI Agent didn't have necessary permissions, what was interesting everything was working on root account
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--profile-directory=Default')
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
driver = webdriver.Chrome(options=chrome_options)
url = 'https://www.google.com'
driver.get(url)
get_url = driver.current_url
print(get_url)
There is lot of possible reasons for the RESPONSE InitSession ERROR unknown error: DevToolsActivePort file doesn't exist error message (as we can see from the number of answers for this question). So let's dive deeper to explain what exactly this error message means.
According to chromedriver source code the message is created in ParseDevToolsActivePortFile method. This method is called from the loop after launching chrome process.
In the loop the driver check if the chrome process is still running and if the ParseDevToolsActivePortFile file was already created by chrome. There is a hardcoded 60s timeout for this loop.
I see two possible reasons for this message:
Chrome is really slow during startup - for example due to lack of system resources - mainly CPU or memory. In this case it can happen that sometimes chrome manage to start in time limit and sometimes not.
There is another issue which prevents chrome to start - missing or broken dependency, wrong configuration etc. In such case this error message is not really helpful and you should find another log message which explain the true reason of the failure.
It happens when chromedriver fails to figure out what debugging port chrome is using.
One possible cause is an open defect with HKEY_CURRENT_USER\Software\Policies\Google\Chrome\UserDataDir
But in my last case, it was some other unidentified cause.
Fortunately setting port number manually worked:
final String[] args = { "--remote-debugging-port=9222" };
options.addArguments(args);
WebDriver driver = new ChromeDriver(options);
As stated in this other answer:
This error message... implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Among the possible causes, I would like to mention the fact that, in case you are running an headless Chromium via Xvfb, you might need to export the DISPLAY variable: in my case, I had in place (as recommended) the --disable-dev-shm-usage and --no-sandbox options, everything was running fine, but in a new installation running the latest (at the time of writing) Ubuntu 18.04 this error started to occurr, and the only possible fix was to execute an export DISPLAY=":20" (having previously started Xvfb with Xvfb :20&).
You can get this error simply for passing bad arguments to Chrome. For example, if I pass "headless" as an arg to the C# ChromeDriver, it fires up great. If I make a mistake and use the wrong syntax, "--headless", I get the DevToolsActivePort file doesn't exist error.
I was stuck on this for a very long time and finally fixed it by adding this an additional option:
options.addArguments("--crash-dumps-dir=/tmp")
I know it's an old question and it already has a lot of answers. However, I ran into this issue, bumped into this thread and none of the proposed solutions helped. After spending a few days(!) on it I finally found a solution:
My problem was that I was using the selenium/standalone-chrome image on a MacBook with M1 chip. After switching to seleniarm/standalone-chromium everything finally started to work.
I had the same issue, but in my case chrome previously was installed in user temp folder, after that was reinstalled to Program files. So any of solution provided here was not help me. But if provide path to chrome.exe all works:
chromeOptions.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
I hope this helps someone =)
In my case it happened when I've tried to use my default user profile:
...
options.addArguments("user-data-dir=D:\\MyHomeDirectory\\Google\\Chrome\\User Data");
...
This triggered chrome to reuse processes already running in background, in such a way, that process started by chromedriver.exe was simply ended.
Resolution: kill all chrome.exe processes running in background.
update capabilities in conf.js as
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['todo-spec.js'],
capabilities: {
browserName: 'chrome',
chromeOptions: {
args: ['--disable-gpu', '--no-sandbox', '--disable-extensions', '--disable-dev-shm-usage']
}
},
};
Old question but a similar issue nearly drove me to insanity so sharing my solution. None of the other suggestions fixed my issue.
When I updated my Docker image Chrome installation from an old version to Chrome 86, I got this error. My setup was not identical but we were instantiating Chrome through a selenium webdriver.
The solution was to pass the options as goog:chromeOptions hash instead of chromeOptions hash. I truly don't know if this was a Selenium, Chrome, Chromedriver, or some other update, but maybe some poor soul will find solace in this answer in the future.
For Ubuntu 20 it did help me to use my systems chromium driver instead of the downloaded one:
# chromium which
/snap/bin/chromium
driver = webdriver.Chrome('/snap/bin/chromium.chromedriver',
options=chrome_options)
And for the downloaded webdriver looks like it needs the remote debug port --remote-debugging-port=9222 to be set, as in one of the answers (by Soheil Pourbafrani):
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--remote-debugging-port=9222")
driver = webdriver.Chrome('<path_to>/chromedriver', options=chrome_options)
Date 9/16/2021
Everything works fine running chrome with selenium locally with python inside the docker hosted ubuntu container. When attempting to run from Jenkins the error above is returned WebDriverException: unknown error: DevToolsActivePort
Environment:
-Ubuntu21.04 inside a docker container with RDP access.
-chromedriver for chrome version: 93
Solution:
Inside the python file that starts the browser I had to set the DISPLAY environment variable using the following lines:
import os
os.environ['DISPLAY'] = ':10.0'
#DISPLAY_VAR = os.environ.get('DISPLAY')
#print("DISPLAY_VAR:", DISPLAY_VAR)
In my case, I was trying to create a runnable jar on Windows OS with chrome browser and want to run the same on headless mode in unix box with CentOs on it. And I was pointing my binary to a driver that I have downloaded and packaged with my suite. For me, this issue continue to occur irrespective of adding the below:
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
System.setProperty("webdriver.chrome.args", "--disable-logging");
System.setProperty("webdriver.chrome.silentOutput", "true");
options.setBinary("/pointing/downloaded/driver/path/in/automationsuite");
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("window-size=1024,768"); // Bypass OS security model
options.addArguments("--log-level=3"); // set log level
options.addArguments("--silent");//
options.setCapability("chrome.verbose", false); //disable logging
driver = new ChromeDriver(options);
Solution that I've tried and worked for me is, download the chrome and its tools on the host VM/Unix box, install and point the binary to this in the automation suite and bingo! It works :)
Download command:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
Install command:
sudo yum install -y ./google-chrome-stable_current_*.rpm
Update suite with below binary path of google-chrome:
options.setBinary("/opt/google/chrome/google-chrome");
And.. it works!
I also faced this issue while integrating with jenkins server, I was used the root user for jenkin job, the issue was fixed when I changed the user to other user. I am not sure why this error occurs for the root user.
Google Chrome Version 71.0
ChromeDriver Version 2.45
CentOS7 Version 1.153
I run selenium tests with Jenkins running on an Ubuntu 18 LTS linux. I had this error until I added the argument 'headless' like this (and some other arguments):
ChromeOptions options = new ChromeOptions();
options.addArguments("headless"); // headless -> no browser window. needed for jenkins
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
ChromeDriver driver = new ChromeDriver(options);
driver.get("www.google.com");
Had the same issue. I am running the selenium script on Google cloud VM.
options.addArguments("--headless");
The above line resolved my issue. I removed the other optional arguments. I think the rest lines of code mentioned in other answers did not have any effect on resolving the issue on the cloud VM.
in my case, when i changed the google-chrome and chromedriver version, the error was fixed :)
#google-chrome version
[root#localhost ~]# /usr/bin/google-chrome --version
Google Chrome 83.0.4103.106
#chromedriver version
[root#localhost ~]# /usr/local/bin/chromedriver -v
ChromeDriver 83.0.4103.14 (be04594a2b8411758b860104bc0a1033417178be-refs/branch-heads/4103#{#119})
ps: selenium verison was 3.9.1
No solution worked for my. But here is a workaround:
maxcounter=5
for counter in range(maxcounter):
try:
driver = webdriver.Chrome(chrome_options=options,
service_log_path=logfile,
service_args=["--verbose", "--log-path=%s" % logfile])
break
except WebDriverException as e:
print("RETRYING INITIALIZATION OF WEBDRIVER! Error: %s" % str(e))
time.sleep(10)
if counter==maxcounter-1:
raise WebDriverException("Maximum number of selenium-firefox-webdriver-retries exceeded.")
It seems there are many possible causes for this error. In our case, the error happened because we had the following two lines in code:
System.setProperty("webdriver.chrome.driver", chromeDriverPath);
chromeOptions.setBinary(chromeDriverPath);
It's solved by removing the second line.
I ran into same issue, i am using UBUNTU, PYTHON and OPERA browser. in my case the problem was originated because i had an outdated version of operadriver.
Solution:
1. Make sure you install latest opera browser version ( do not use opera beta or opera developer), for that go to the official opera site and download from there the latest opera_stable version.
Install latest opera driver (if you already have an opera driver install, you have to remove it first use sudo rm ...)
wget https://github.com/operasoftware/operachromiumdriver/releases/download/v.80.0.3987.100/operadriver_linux64.zip
unzip operadriver_linux64.zip
sudo mv operadriver /usr/bin/operadriver
sudo chown root:root /usr/bin/operadriver
sudo chmod +x /usr/bin/operadriver
in my case latest was 80.0.3987 as you can see
Additionally i also installed chromedriver (but since i did it before testing, i do not know of this is needed) in order to install chromedriver, follow the steps on previous step :v
Enjoy and thank me!

I came across the same problem, in my case there are two different common user userA and userB in Linux system.
userA first run the selinium programe which start chrome browswer with ChromeDriver successfully, when it came to userB, the DevToolsActivePort file doesn't exist error occur.
I tried the --remote-debugging-port=9222 option, but it lead to a new exception:
selenium.common.exceptions.WebDriverException: Message: chrome not reachable
The I ran google-chome directory and see the following error:
mkdir /tmp/Crashpad/new: Permission denied (13)
The I search the problem and got this:

Thanks to #johncylee.
I tried to add the below in the serenity.conf file to always load the chrome browser with these options but it fails to load the browser. When I pass in the below options via command line like so "gradle test -Dchrome.switches="--no-sandbox,--ignore-certificate-errors,--homepage=about:blank,--no-first-run" the browser starts successfully.
"-Dchrome.switches="--no-sandbox,--ignore-certificate-errors,--homepage=about:blank,--no-first-run"
Is there a way to always open chrome browser without having to pass this via command line or have the chrome driver as part of the framework?
serenity.conf
#
# WebDriver configuration
#
webdriver {
driver = chrome
autodownload = true
}
#headless.mode = true
serenity.test.root = java
#
# Chrome options can be defined using the chrome.switches property
#
chrome.switches = """--start-maximized;--test-type;--no-sandbox;--ignore-certificate-errors;
--disable-popup-blocking;--disable-default-apps;--disable-extensions-file-access-check;
--disable-web-security;--incognito;--disable-infobars,--disable-gpu,--homepage=about:blank,--no-first-run"""
Thanks!
Try
chrome {
switches = "--start-maximized;--enable-automation;--no-sandbox;--disable-popup-blocking;--disable-default-apps;--disable-infobars;--disable-gpu;--disable-extensions;"
preferences {
download: "{prompt_for_download: false,directory_upgrade: true,default_directory:'${user.dir}/downloaded-files'}"
}
}
Thank you!

Below is the information on manned drivers in serenity.
Serenity reduces the amount of code you need to write and maintain when you write web tests. For example, it takes care of creating WebDriver instances, and of opening and closing the browser for you. The following is a very simple Selenium web test using Serenity:
So whenever I try to use my Chrome settings (the settings I use in the default browser) by adding
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\Users\... (my webdriver path)")
driver = webdriver.Chrome(executable_path="myPath", options=options)
it shows me the error code
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes n 16-17: truncated \UXXXXXXXX escape
in my bash. I don't know what that means and I'd be happy for any kind of help I can get. Thanks in advance!
The accepted answer is wrong. This is the official and correct way to do it:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_argument(r"--user-data-dir=C:\path\to\chrome\user\data") #e.g. C:\Users\You\AppData\Local\Google\Chrome\User Data
options.add_argument(r'--profile-directory=YourProfileDir') #e.g. Profile 3
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")
To find the profile folder on Windows right-click the desktop shortcut of the Chrome profile you want to use and go to properties -> shortcut and you will find it in the "target" text box.
To get the path, follow the steps below.
In the search bar type the following and press enter
This will then show all the metadata. There find the path to the profile
As per your question and your code trials if you want to open a Chrome Browsing Session here are the following options:
To use the default Chrome Profile:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\Default")
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")
Note: Your default chrome profile would contain a lot of bookmarks, extensions, theme, cookies etc. Selenium may fail to load it. So as per the best practices create a new chrome profile for your #Test and store/save/configure within the profile the required data.
To use the customized Chrome Profile:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2")
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")
Here you will find a detailed discussion on How to open a Chrome Profile through Python
This is how I managed to use EXISTING CHROME PROFILE in php selenium webdriver.
Profile 6 is NOT my default profile. I dont know how to run default profile. It is IMPORTANT not to add -- before chrome option arguments! All other variants of options didnt work!
<?php
//...
$chromeOptions = new ChromeOptions();
$chromeOptions->addArguments([
'user-data-dir=C:/Users/MyUser/AppData/Local/Google/Chrome/User Data',
'profile-directory=Profile 6'
]);
$host = 'http://localhost:4444/wd/hub'; // this is the default
$capabilities = DesiredCapabilities::chrome();
$capabilities->setCapability(ChromeOptions::CAPABILITY, $chromeOptions);
$driver = RemoteWebDriver::create($host, $capabilities, 100000, 100000);
To get name of your chrome profile, go to chrome://settings/manageProfile, click on profile icon, click "Show profile shortcut on my desktop". After that right click on desktop profile icon and go to properties, here you will see something like "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 6".
Also I recommend you to close all chrome instances before running this code. Also maybe you need to TURN OFF chrome settings > advanced > system > "Continue running background apps when Google Chrome is closed".
None of the given answers were working for me so I researched a bit and now the working code is for is this one. I copied the user dir folder from Profile Path from chrome://version/ and made another argument for the profile as shown below:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_argument('user-data-dir=C:\\Users\\gupta\\AppData\\Local\\Google\\Chrome\\User Data')
options.add_argument('profile-directory=Profile 1')
driver = webdriver.Chrome(executable_path=r'C:\Program Files (x86)\chromedriver.exe', options=options)
driver.get('https://google.com')
Are you sure you are meant to be putting in the webdriver path in the user-data-dir argument? That's usually where you put your chrome profile e.g. "C:\Users\yourusername\AppData\Local\Google\Chrome\User Data\Profile 1\". Also you will need to use either double backslashes or forward slashes in your directory path (both work). You can test if your path works by using the os library
e.g.
import os
os.list("C:\\Users\\yourusername\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 1")
will give you the directory listing.
I might also add that occasionally if you manage to crash chrome while running webdriver with a nominated user profile, that it seems to record the crash in the profile and the next time you open chrome, you get the Chrome prompt to restore pages after it exited abnormally. For me personally this had been a bit of headache to deal with and I no longer use a user profile with chromedriver because of it. I could not find a way around it. Other people have reported it here, but none of their solutions seemed to work for me, or were not suitable for my test cases. https://superuser.com/questions/237608/how-to-hide-chrome-warning-after-crash
If you don't nominate a user profile it seems to create a new (blank) temporary one each time it runs
Make sure you've got the path to the profile right, and that you double escape backslashes in said path.
For example, typically the default profile on windows is located at:
"C:\\Users\\user\\AppData\\Local\\Google\\Chrome\\User Data\\Default"
I managed to launch my chrome profile using these arguments:
ChromeOptions options = new ChromeOptions();
options.addArguments("--user-data-dir=C:\\Users\\user\\AppData\\Local\\Google\\Chrome\\User Data");
options.addArguments("--profile-directory=Profile 2");
WebDriver driver = new ChromeDriver(options);
You can find out more about the web driver here
You simply have to replace the '\' to '/' in your paths and that'll resolve it.
Get profile name by navigating to chrome://version from your chrome browser (You'll see Profile Path, but you only want the profile name from it (e.g. Profile 1)
Close out all Chrome sessions using the profile you want to use. (or else you will get the following error: InvalidArgumentException)
Now make sure you have the code below (Make sure you replace UserFolder with the name of your userfolder.
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Users\\EnterYourUserFolder\\AppData\\Local\\Google\\Chrome\\User Data") #leave out the profile
options.add_argument("profile-directory=Profile 1") #enter profile here
driver = webdriver.Chrome(executable_path="C:\\chromedriver.exe", chrome_options=options)
this worked for me 100% and it showed up my selected profile.
import os
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
# path of your chrome webdriver
dir_path = os.getcwd()
user_profile_path = os.environ[ 'USERPROFILE' ]
#if "frtkpr" which is ll be your custom profile does not exist it will be created.
option.add_argument( "user-data-dir=" + user_profile_path + "/AppData/Local/Google/Chrome/User Data/frtkpr" )
driver = webdriver.Chrome( dir_path + "/chromedriver.exe",chrome_options=option )
baseUrl = "https://www.facebook.com/"
driver.maximize_window()
driver.get( baseUrl )
I need to test Firefox using an extension. I want to automate the test and visit several websites.
I installed Selenium and it opens in geckodriver. However, the extension is not there. I can install it manually from about:debugging but the problem is that I want the Selenium test to launch the gecko driver while the extension is already there. How to do this? How to install the extension permanently in the geckodriver so it is there when I launch the geckodriver from selenium?
EDIT:
I also tried to install the extension (add it to the browser) from the Firefox extensions websites. It gets added but once I close the gecko window, the extension disappear in the next run. How to install it permanently?
Note: OP didn't specify a language, so this answer is for Python. The other Selenium WebDriver language bindings have similar mechanisms for creating profiles and adding extensions.
You can install the Extension each time you instantiate the driver.
First, download the extension (XPI file) you want from: https://addons.mozilla.org.
Then, in your code... create a FirefoxProfile() and use the add_extension() method to add the extension. Then you can instantiate a driver using that profile.
For example, this will launch Firefox with a newly created profile containing the "HTTPS Everywhere" extension:
from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.add_extension(extension='https_everywhere-2019.1.31-an+fx.xpi')
driver = webdriver.Firefox(firefox_profile=profile)
You need to launch geckdriver with an exisitng profile by specifying the profile path of firefox
For python you can do it by this:
profile = FirefoxProfile('/home/student/.mozilla/firefox/gwi6uqpe.Default') // change this path
browser = webdriver.Firefox(firefox_profile=profile)
For C# you can do this:
string path = #"C:\Users\username\AppData\Local\Mozilla\Firefox\Profiles\myi5go1k.default";
FirefoxProfile ffprofile = new FirefoxProfile(path);
Driver = new FirefoxDriver(ffprofile);
I found that this was warking for me:
from selenium import webdriver
driver_path = r"G:\Libs\geckoDriver\firefox\geckodriver.exe"
driver = webdriver.Firefox(executable_path=driver_path)
path = r"G:\Libs\ext\uBlock0_1.38.7b5.firefox.signed.xpi"
driver.install_addon(path, temporary=True)
driver.profile = webdriver.FirefoxProfile()
driver.profile.add_extension(path)
driver.profile.set_preference("security.fileuri.strict_origin_policy", False)
driver.profile.update_preferences()`enter code here`

You can install an extension/addon permanently within a specific Firefox Profile and use it. To achieve that you need follow the below mentioned steps:
You need to create a new Firefox Profile manually (e.g. FirefoxExtensionProfile) following the instructions at Creating a new Firefox profile on Windows.
Open a Firefox Browsing session manually and invoke the url https://addons.mozilla.org/en-US/firefox/
In the Search Box search for an extension e.g. HTTPS Everywhere.
Click on the search result and install / enable (incase previously installed and currently disabled) the extension.
Now you can use the following Java solution to open the Firefox Profile FirefoxExtensionProfile containing the extension HTTPS Everywhere
Code Block:
package A_MozillaFirefox;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.firefox.ProfilesIni;
public class A_FirefoxProfile_dc_opt {
public static void main(String[] args) {
System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
ProfilesIni profile = new ProfilesIni();
FirefoxProfile testprofile = profile.getProfile("FirefoxExtensionProfile");
FirefoxOptions opt = new FirefoxOptions();
opt.setProfile(testprofile);
WebDriver driver = new FirefoxDriver(opt);
driver.get("https://www.google.com");
}
}
