Unable to use Cloudflare Captcha in Firefox

Basically see above - I’m unable to login to Cloudflare dash because captcha is never approving me - it keeps spinning and spinning.

While looking on console, I see multiple requests to similar URLs


every single one of the is getting 401 reply.
(here was another screenshot, but I can’t upload it, because I’m a new user)

It would be OK if I could not log in to Cloudflare, but this is affecting ALL applications that are using cloudflare captcha, including Postman.

Any help with this would be greatly appreciated.

by eliminating my extensions in browser, I came to conclusion that JavaScript Error Notifier extension is the cause for that. Do you have that extension?


For me it was the useragent switcher i was using
