from selenium import webdriver;
browser= webdriver.Firefox();
browser.get('http://www.seleniumhq.org');
When I try to run this code, it gives me an error message:
Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line.
Any thoughts-highly appreciated!
This error message...
Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line.
...implies that the GeckoDriver was unable to find the Firefox binary at the default location. Additionally you haven't passed the moz:firefoxOptions.binary capability.
Solution
Possibly within your system firefox is installed in a custom location and these cases you need to pass the absolute path of the Firefox binary through the moz:firefoxOptions.binary capability as follows:
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
options = Options()
options.binary_location = r'C:\Program Files\Mozilla Firefox\firefox.exe'
driver = webdriver.Firefox(executable_path=r'C:\WebDrivers\geckodriver.exe', options=options)
driver.get('http://google.com/')

Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided
Firefox was not installed on my system at all. That's why this error came up.
same issue here:
Environment
OS: Mac
Not install Firefox application
has installed geckodriver, can found in PATH
Error Reason: Not installed Firefox
Solution: (goto firefox official site to download and) install Firefox
Before this ensure that path variable has include for geckodriver click here to download driver and run below python script.
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
options = Options()
options.binary_location = r'C:\Program Files\Mozilla Firefox\firefox.exe'
driver = webdriver.Firefox(options=options)
driver.get('http://google.com/')
I have uninstalled firefox and installed it again which resolved my issue.
You should download appropriate web driver from https://github.com/mozilla/geckodriver/releases and put it into folder where your py file is. Also you can put it anywhere as long as the location of the file it is in your system path.
Selenium uses a web driver (a specific one for each web browser) in order to communicate with the browser installed on your system (Firefox in your case).
To use Firefox, you have to:
Download its web driver from
https://github.com/mozilla/geckodriver/releases
Put the web driver in a specific location in the file system (same folder as the python script for example)
Add the web driver location path when initializing in the python code.
So the final code would look like this:
from selenium import webdriver
browser = webdriver.Firefox('./geckodriver')
browser.get('https://www.python.org/')
Note: Sometimes a newer version of the web driver isn't compatible with an older version of the browser installed on your system.
I have encountered the same problem (Windows, Firefox v99, Selenium 4.1.4, geckodriver 0.31.0), the path to exe file and the driver initialisation were set correctly, solved the issue by changing the win32 by win64 version of geckodriver
as a side note for selenium/firefox (but with C#, not Python), this issue is quite relevant now in the sense that firefox location looks to be stored in windows in a new regedit location. Indeed geckodriver is looking in regedit location documented here:
HKEY_LOCAL_MACHINE\SOFTWARE WOW6432Node\Mozilla\Mozilla Firefox\[VERSION]\Main\PathToExe
HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Mozilla Firefox\[VERSION]\Main\PathToExe
Source:
https://developer.mozilla.org/en-US/docs/Web/WebDriver/Capabilities/firefoxOptions
when on my machine it is there:
HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Mozilla Firefox 109.0\bin
With the version number stored here:
HKEY_LOCAL_MACHINE\SOFTWARE\mozilla.org\Mozilla
and I set the selenium driver with C# Api with (path hardcoded for the poc):
var options = new FirefoxOptions();
...
options.BrowserExecutableLocation = #"C:\Program Files\Mozilla Firefox\firefox.exe";
Driver = new FirefoxDriver(options);

You need to download geckodriver.
https://github.com/mozilla/geckodriver/releases
from selenium import webdriver;
browser= webdriver.Firefox('./geckodriver');
browser.get('http://www.seleniumhq.org');
I trying to use selenium in jupyter notebook on Firefox. I have installed the geckodriver in /usr/bin directory .When I run my code it says:
WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
if I run the command %env PATH following output is displayed:
$PATH:/usr/bin/
from selenium import webdriver
browser = webdriver.Firefox()
I have even tried
browser=webdriver.Firefox(executable_path=r'/usr/bin/geckodriver')
Can somebody help me solve this?
I hope you are working with geckodriver on the local machine and providing the absolute path for the driver to run, This can be done automatically using webdriver-manager python
Advantages of using it are-
You don't have to give the path every time to run code.
Makes the code portable and easy to run on any machine without checking for geckodriver or chromedriver.
pip install webdriver-manager
Now the above code in the question can be changed to work simply with,
from selenium import webdriver
from webdriver_manager.firefox import GeckoDriverManager
driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())
If the above doesn't help, try doing this.
autoinstaller for geckodriver-
pip install geckodriver-autoinstaller
from selenium import webdriver
import geckodriver_autoinstaller
geckodriver_autoinstaller.install() #checks for driver or install it. driver =
webdriver.Firefox() driver.get("python.org")
this worked fine for me, otherwise, try to give a full path after downloading the latest geckodriver binary file.
Try to implement this with a Maven project so you can add dependencies in the pom.xml file. so you dont have to give the path each time. Refer this article here.Its in java but will help.
I am using Selenium with Robot Framework to run an Electron application. The application is built to read a configuration file from the user data directory. As far as I understand, this is the location where this file should be stored.
The electron main process reads the configuration file:
const localConfigFile = path.join(app.getPath('userData'), 'config.json');
const localConfig = fs.existsSync(localConfigFile) ? require(localConfigFile) : {};
The built production version works just fine and reads the file as expected, but when starting it from Robot using SeleniumLibrary, the file is not read. This leads me to believe it's a problem with Robot, Selenium or ChromeDriver.
Robot creates the webdriver using SeleniumLibrary:
Create Webdriver Remote desired_capabilities=${starting_parameters} command_executor=http://127.0.0.1:9515
Where starting parameters are simply:
{ "chromeOptions": {"binary": <binary_location> }}
Chromedriver is started as a separate process from /usr/bin/chromedriver where it has been installed and uses the default port 9515.
The versions that I am using are:
ChromeDriver 2.36.540471 (9c759b81a907e70363c6312294d30b6ccccc2752)
"electron": "^6.0.2"
"electron-builder": "^21.2.0"
robotframework==3.2.1
robotframework-seleniumlibrary==3.3.1
Ubuntu 18.04.4 LTS
Experienced the same problem. Finally changing the Chromedriver's user-data-dir argument to Electron's userDataDir solved the problem.
options.add_argument('--user-data-dir=' + str(app_config_path()))
I found out the problem by using Spectron and logging the Electron main console. In general I would advice using Spectron instead of Robot to test Electron apps.
The issue is that the user data directory was not the same as the Electron default. When running the application through Chromedriver, the user data directory is changed to /tmp/somethingsomething so naturally the file under ~/.config/app-name was not found.
My solution was to use Electron'ss application data directory instead:
app.getPath('appData')
By default this is one directory up from the user data directory, but remains the same when running through Chromedriver.
I ran into a problem while working with VS2015 + Ironpython + Selenium:
the ironpython 2.7.7 has pip installed selenium,the scripts:
import os
import selenium
from selenium import webdriver
from time import sleep
browser = webdriver.Ie()
browser.get('https://stackoverflow.com/')
However,when the scrpts ran to browser = webdriver.Ie(), it throws a exception:
Message: The executable IEDriverServer.exe needs to be available in
the path.
I try to put the IEDriverServer.exe to many paths including the ironpython's install path,the script's root path,the system32 folder,etc,but can't solve this problem.
PS:python2.7 with selenium can work properly,so did C# with selenium.but I just want try ironpython with selenium,that's the point
Put the IEDriverServer.exe any where within your system and mention the absolute path of the IEDriverServer.exe as follows :
from selenium import webdriver
browser=webdriver.Ie(executable_path=r'C:\path\to\IEDriverServer.exe')
browser.get('https://stackoverflow.com/')
While using AppiumLibrary with RobotFramework, I am getting below error.
Error: importing test library 'AppiumLibrary' failed:
ImportError: No module named switch_to
Here,PYTHONPATH: /usr/local/lib/python2.7/dist-packages/selenium-2.44.0-py2.7.egg
To resolve above error I want to try solution mentioned at link "https://github.com/appium/appium/issues/2625" which asks to remove the lower version of selenium.
I have two selenium folders at below location.
Selenium folders:
1)/usr/local/lib/python2.7/dist-packages/selenium
2)/usr/local/lib/python2.7/dist-packages/selenium-2.44.0.egg-info
How can I remove the the selenium other than 2.44?
No process was required to uninstall Selenium.
I simply deleted the directory "/usr/local/lib/python2.7/dist-packages/selenium". This resolved my error with Robot Framework.
