Its happening on both my laptop and big computer. FF updated to latest on both, only extensions Ublock Origin, Block HTML5 Autoplay and Zotero. Doesnt work in different networks.

Accessing the same sites with Brave or Vivaldi, no problems. It sucks ass and I'm certainly not the only one with this problem. Why the heck does this problem keep popping up with FF periodically, judging by both FF and CF support forums?

CF's captcha works by activating obscure browser features banking that bots haven't implemented them or behave just differently enough to stick out as unusual. Try creating a new profile with default settings, and if that works try adding your customizations back one by one until you find the one breaking CF.
