Firefox: Gah. Your tab just crashed. since yesterday
I suddenly can't use Firefox (v119.0) anymore, even though I didn't install any new software on my system. I noticed however, that Bitdefender updated. Since then I get the above error for every single link, and even the Firefox-Addon page just stays empty (I can access the "about:config" and the "about:crashes" though).
I tried everything on the Firefox side including uninstalling, manually deleting everything Mozilla related and re-installing Firefox. To no avail. I have installed Brave since in order to access this page.
Can anybody help me?
