Having Cloudflare work with Firefox would be much more useful. Having horrendous problems with CF+Firefox this past month, always get stuck in the infinite captcha loop.

Cloudflare has pretty much banned me using FF as of late and it sucks ass in a bad way.

Works fine for me. Have you made sure it's not caused by an extension?

Yeah, spoofing user agent can cause this for instance.

cloudflare is kinda aggressive lately for me, this happens in both chrome/ium and firefox. the solution is to pass the captcha once from a different browser or device on the same network

I had that issue for a while and it turns out I forgot I had an extension changing my user agent. After I changed it back to default everything worked fine.

I did that too but it sometimes works, sometimes doesn't, it's nuts

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.

Is there a bug already reported for this?

I have no idea, but the issue has been periodically reported in FF forums at least since '22.
