hi thank you for the quick reply.

this was how i fixed it for now after a google search i changed " plugin.scan.plid.all" to false

im running windows 11 139.0.4 (64-bit) of firefox (a re-install of firefox didnt fix the issue

im running the exact same setup using the same firefox account+plugins on my laptop and i didnt have the issue.

i have no idea why going to about:config and changing plugin.scan.plid.all" to false worked but i thought i would mention what worked for me

Hello, I'm having the same problem, but on Windows 10. It's a fresh windows installation and I tried some solutions: reinstalling firefox, deleting cache, refreshing firefox, private windows, no add on, trouble shoot mod. Nothing helped. The problem occurs only on twitch. The solution above didn't help.
