I noticed that the ChromeDriver in Headless mode does not receive the default Profile that I created, and for this project it is necessary because I need the cookies and sessions always saved .. searching I found some topics that said Chrome in Headless mode does not accept preferences. It is true?
Another thing I noticed in Headless mode is that some sites do not identify ChormeDriver like Google Chrome, which is pretty weird. Is there any way to force this in Chrome Options?

I have a Selenoid Firefox container running some tests but new browser versions are giving me issues.
Since Firefox 103.0 Cross-site tracking cookies are blocked by default and I am looking for a way to add a website exception in Privacy & Security > Cookies and Site Data using Firefox capabilities / Options but nothing seems to do the trick.
A good example of website that causes issues is https://teams.microsoft.com where firefox will now ask you if you "Really want to accept cookies from there ?" which I am trying to bypass by setting website exception in advance.
Done it by selecting a profile at geckodriver start instead of letting it generate one: Add args: ["-profile", "/binary/nameoffirefoxprofile"] to capabilities pref in your code. For this you need to get a firefox profile folder and copy it to your container first. If this works it will replace the generated rust_mozprofile_someID of geckodriver.
I disabled loading images in chrome while using webdriver with selenium now cant enable it.
I was using python to webscrape on instagram so thought it would be a good idea to disable images.
The commands i used:
options = webdriver.ChromeOptions()
options.add_argument("--disable-gpu=true")
options.add_argument("--blink-settings=imagesEnabled=false")
And now I cannot change it from chrome settings.
Screenshot of chrome settings page.
Please Help.
Edit: This happens only in my default Chrome Profile. Other Profiles work fine even though the profile I use for selenium is a different one.
After a long day on google finally found the solution.
options.add_experimental_option("prefs", {'profile.managed_default_content_settings.images': 1})
I have been executing automation scripts for last 6 months without any issues. Suddenly chrome browser shows captcha screen and shows message that please confirm are you human ?.
Below that it states 2 points 1.JavaScript might be disabled 2. your cookies are not supported .I enabled both of the Java script and cookies but no luck.
I tried to execute older version of chrome browser also but I am getting same captcha screen in the older version of browser too.
The good thing is that I am not getting captcha screen in Firefox and edge browser. I am getting it only in the chrome browser.
May I know if chrome has introduced any functionality like if we execute automation scripts and it shows captcha screen because why I am getting this doubt that firefox and edge is not showing captcha screen.
I can handle it with FF web driver (selenium python) but when I change phantomjs the driver .it didnt handle it. is it possible to handle it?
the program must work on server so what must I do?
In short, no, this is not currently possible. The PhantomJS ghostdriver does not implement the primitives for handling alerts/prompts. See https://github.com/detro/ghostdriver/issues/20
This is also unlikely to change since development of PhantomJS has been discontinued.
the program must work on server so what must I do?
Your best option is to use the headless versions of Chrome or Firefox, which can run in a headless environment like PhantomJS just fine. Both Chrome (chromedriver) and Firefox (geckodriver) implement the necessary primitives for handling alerts/prompts.
Another option is that you can use a virtual screen program (e.g. xvfb) to enable you to use a headed browser in a headless environment.
Can anyone explain what is running selenium tests in headless mode in jenkins?
As per comment it's a way of running tests in a browser that doesn't have a GUI attached to it
What is a headless browser? (Quoted from ToolsQA)
Headless browser is a term used to define browser simulation programs
which do not have a GUI. These programs behave just like a browser but
don’t show any GUI. Famous ones are HtmlUnit and the NodeJs headless
browsers. There are a good number of more browsers too.
What is the use of Headless browsers?
Headless browsers are typically used in following situations
You have a central build tool which does not have any browser installed on it. So to do the basic level of sanity tests after every
build you may use the headless browser to run your tests.
You want to write a crawler program that goes through different pages and collects data, headless browser will be your choice. Because
you really don’t care about opening a browser. All you need is to
access the webpages.
You would like to simulate multiple browser versions on the same machine. In that case you would want to use a headless browser,
because most of them support simulation of different versions of
browsers. We will come to this point soon.
Things to pay attention to before using headless browser
Headless browsers are simulation programs, they are not your real
browsers. Most of these headless browsers have evolved enough to
simulate, to a pretty close approximation, like a real browser. Still
you would not want to run all your tests in a headless browser.
JavaScript is one area where you would want to be really careful
before using a Headless browser. JavaScript are implemented
differently by different browsers. Although JavaScript is a standard
but each browser has its own little differences in the way that they
have implemented JavaScript. This is also true in case of headless
browsers also. For example HtmlUnit headless browser uses the Rihno
JavaScript engine which not being used by any other browser.
