Firefox Not Browsing At All On Windows 11

This is strange behavior started randomly, I have been using the same OS (Windows 11) and Firefox using same user login like from past 04 years on laptop, never had such issue! I am out of clue what happened ? suddenly it just stopped browsing anything, its updating, downloading its themes, plugins, just not browsing !! no matter what URL you type in its just dead blank!

I have tried everything available over internet to fix it , its just not working!

  • I tried refreshing Firefox
  • I tried removing and reinstalling
  • I tried restarting machine a ton of times
  • I tried every youtube video suggested commands to run over cmd as admin.
  • I tried switching windows user, logged on to other one! its the same!
    What should I do now ??? :frowning:
