You can try launching Firefox in Safe Mode, which disables all extensions and themes. To do this, click on the menu button, select "Help," and then choose "Restart with Add-ons Disabled." If Twitch works in Safe Mode, an extension is likely causing the problem. Additionally, ensure that both Firefox and any security software on your device are fully updated, as outdated versions can sometimes lead to compatibility issues.

I am having the same issue

Safe Mode does not help, clearing all data and resetting the browser doesnt help either
I dont use any security software besides windows onboard defender which is all up to date, same for windows

This really needs to be looked at

Using 140.0.4 ESR here, couldn't login anymore 4 days ago. Main OS is Linux, Windows as backup.
Message unsupported browser. Real java message : erreur 400 malformed URL

Safe mode : NOT OK.
Deleted Mozilla folders : NOT OK. (What !?)

I created another user account : OK
Login under Windows with the same version/config/extensions/skin/... as Linux : OK

Back to main Linux account.
Installed and tried Chromium : OK
Tried FF private/incognito mode : OK !

What's the matter with Firefox ?

So do I need another FF account to fix this? I'm about to give up on FF and move to brave.
