There has been found a temporary workaround(for advanced users only):

Go to "about:config". Search for "network.http.http3.enabled". Set value for "network.http.http3.enabled" to "false". Restart Firefox.

After this bug gets updated, you should set the value back to "true".

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.
