Hi Everyone,

Environment details: OS: Windows7 (64bit) Firefox Version : 90.0.2 (64bit)

I am trying to launch Firefox as a different user on my machine and trying to open a web page which uses Widows Single sing on. I want the browser to use the Run as account credential which I used to launch the browser to be used for the Webpage authentication. Tried setting the following configs network.automatic-ntlm-auth.trusted-uris and network.automatic-ntlm-auth.trusted-uris but didn't worked out. Any Idea how to force the browser to use the run as credential to authenticate into a webpage page that uses windows Single sign on.

Thank You, Kalidhas P

Thank you, Don't have the option "Allow Windows single sign-on for Microsoft, work, and school accounts" anywhere.

Oups, it's in version 91. Sorry, you have to wait 2 weeks to test it out.
