I have cleared the cache and cookies and I have reinstalled Firefox but I am not able to connect to any site. Reinstalling fixed the issue for about 15 minutes but it is now not connecting again. I remoted onto my work machine, and that machine also has the same issue with fire fox. Chrome is working fine on both machines. I have restarted my machines and my router.

Disable HTTP3 support by disabling 'network.http.http3.enabled' key in about:config and then restart Firefox. Worked for me.

Hi

I appreciate that you may have done this already, but please can you restart Firefox which should resolve this issue.

Earlier today, Firefox became unresponsive due to a change in defaults by a cloud provider which triggered a Firefox HTTP/3 bug. We disabled the configuration change and confirmed this fixed the issue.
