Firefox is hanging.
Firefox worked fine for about 20 minutes but now it's hanging. I tried downloading the latest version, changed the places.sqlite filename to places.sqlite.old but nothing works. Help!

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.

From HN: What worked for me was disabling HTTP3 support with the 'network.http.http3.enabled' key in about:config and then restarting Firefox. Seems like it's stuck in the 'SocketThread', repeatedly doing this:
2022-01-13 08:20:53.075936 UTC - [Parent 4106991: Socket Thread]: V/nsHttp Http3Stream::OnReadSegment count=333 state=4 [this=7f6e295623a0]
Thanks! How do I do that?

Open a new tab, type about:config, there type network.http.http3.enabled and change it to false.
Hi
I appreciate that you may have done this already, but please can you restart Firefox which should resolve this issue.
