HTTP Basic Auth via URL in Firefox does not work?


I know that normally you can login to sites that require HTTP basic authentication with Selenium by passing the username and password in the URL, e.g.:"");

I’ve been running a Selenium test with Firefox 2 or 3 and there I still get the “Authentication Required” dialog window?

Update: It seems not to be a Selenium problem but rather a Firefox issue. If I enter the URL manually within FF I’ll get the authentication dialog, but if I enter the URL in Opera, my page is displayed without showing an authentication dialog.

Contributing to Druska´s answer, you can do the same configuration using Selenium 2 API:

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.http.phishy-userpass-length", 255);
new FirefoxDriver(profile);

This approach is simpler and you do not have to ask every developer to change their Firefox configuration. I only tested with the Firefox driver.


For some reason (maybe the ones explained at, the above solution does not work with newer versions of Firefox. Here is what works for me now (tested with Firefox 19.0.2):

  1. Install AutoAuth Firefox plugin;
  2. Visit the site where the authentication is needed. Enter your username and password and make sure to choose to save the credentials;
  3. Save AutoAuth installation file at your hard drive: at the plugin page, right click at “Add to Firefox” and “Save link as”;
  4. Instantiate Firefox webdriver as following:

    FirefoxProfile firefoxProfile = new ProfilesIni().getProfile("default");
    File pluginAutoAuth = new File("src/test/resources/autoauth-2.1-fx+fn.xpi");
    return new FirefoxDriver(firefoxProfile);

Make sure to instantiate the pluginAutoAuth File with the correct path where you saved the plugin installation. If you do not feel comfortable using the default profile, you can use Firefox Profile Manager and create one specific to your tests.
