How to set proxies with Username and Password in FirefoxDriver

Setting up Custom Firefox Profile to run Selenium Tests on Desktop Firefox

Even though Selenium – WebDriver – FirefoxDriver – Proxy with Basic/Kerberos Authentication didn’t work, you can achieve this with an alternate step that overrides Firefox browser Proxy Authentication.

The alternate step is nothing but allowing WebDriver to run tests on default/custom Firefox profile rather than running from FirefoxDriver.

In Selenium 2.0 (WebDriver) every popular browsers has its own selenium drivers to run tests.

Let us go with the concept now…

Create Firefox Profile Manager

Important: Before you can start the Profile Manager, Firefox must be completely closed.

1. At the top of the Firefox window, click on the Firefox button and then select Exit
2. Press Win + R (click the Windows Start button and select Run... on Windows XP).
3. In the Run dialog box, type in:
    firefox.exe -p
4. Click OK.

5. Now, create the firefox profile "myProjectProfile".

If the Profile Manager window does not open, Firefox may have been running in the background, even though it was not visible. Close all instances of Firefox or restart the computer and then try again.

Add this New Firefox Profile on your code

ProfilesIni profile = new ProfilesIni();
FirefoxProfile myprofile = profile.getProfile("myProjectProfile");
WebDriver driver = new FirefoxDriver(myprofile);

Firefox configuration settings

This works fine without prompting any authentication when you do the following settings..

1) Type "about:config" on your FF url
2) Now type "Proxy" in the search field
3) Make sure "signon.autologin.proxy" is set "true" (By default it is "false")


  1. I was looking for a Proxy Prompt solution for some time now. Noone has EVER mentioned the "signon.autologin.proxy" setting!

    This solved my problem. THANK YOU!

  2. I followed the above instructions carefully but the authentication dialog box still appears and I am required to click the "Ok" button before the test will continue execution using the saved credentials.

    I'm using Firefox 23.0.1

    1. use autoauth add on available in https://addons.mozilla.org/en-us/firefox/addon/autoauth/developers

    2. This was the only solution that worked for me

  3. Did anyone get any solution on this?

  4. These queries seems to be new for me :) May be you would have missed any of those steps.

  5. I also got the same problem.
    On windows authentication, the username and password is typing automatically.
    But its not clicking "OK" button.

  6. I tried using web driver navigate and get..But control is not coming out of both the api to use other webdriver api to click enter key

  7. Hey, is there any update on this?

  8. Same issue i am facing...any solutionplease?

  9. Try to set network.auth.force-generic-ntlm = true in about:config
    Or add required URLs to network.automatic-ntlm-auth.trusted-uris (comma-separated)
