Having consistent problem of Anubis not working at all in Firefox

Describe the bug Having consistent problem of Anubis not working at all in Firefox. I'm not even getting "You are a bot" error. Just "checking connection".

To Reproduce In my browsers: go to any site where Anubis will be triggered (I'm yet to see any site where Anubis will let me through).

Expected behavior At least an error.

Additional context Not sure if it's related, but I'm having similar issues with Cloudflare's checkbox for some years now. Although it just error out with "takes too long". Google ones were working correctly last time I encountered them.
