HTTP Basic Auth via URL in Firefox does not work?

Question

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.:

sele

I have a solution for Firefox and Internet Explorer.

For Firefox, you need to go into about:config and create the integer network.http.phishy-userpass-length with a length of 255. This tells Firefox not to popup an authentication box if the username and password are less than 255 characters. You can now use http://user:pass@domain.com to authenticate.

For Internet Explorer, you must edit the registry. In the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_HTTP_USERNAME_PASSWORD_DISABLE, create the DWORD values iexplore.exe and explorer.exe and make sure their values are 0.

I had to override NTLM authentication aswell. To NTLM authenticate using the HTTP basic authentication syntax in Firefox, simply specify the domains being used in the Firefox config string network.automatic-ntlm-auth.trusted-uris (accompanying the first config option). This will work in IE with the registy edit alone.
