"Firefox 96.0 hangs after a while - loses connectivity": workaround for rhbz 2040189

[Felix Schwarz]

Hi,

I guess this might affect quite a few people so I hope I can save you a few 
minutes to find the workaround:

Firefox 96.0 hangs after a while - loses connectivity
https://bugzilla.redhat.com/show_bug.cgi?id=2040189

upstream bug:
Infinite loop in HTTP3 hangs socket thread
https://bugzilla.mozilla.org/show_bug.cgi?id=1749908

Workarounds (from the upstream bug):
> If anyone need to fix it, please open "about:config" in a new tab.
> Search : "network.http.http3.enabled"
> change to false, then restart firefox.
> Other workaround: Go to preferences -> Firefox Data Collection and uncheck everything. Then restart Firefox

Similar issue with 95 on Fedora 34 Re: "Firefox 96.0 hangs after a while - loses connectivity": workaround for rhbz 2040189

Have 4 Fedora 34 machines in room, and the firefox was 
very flakey. But would work on some and not on others, 
and then switch. Found this solution that seems to fix it 
for now??

Go to settings and search Firefox Data Collection and 
uncheck allow firefox to install and run studies. 
Then restart firefox??

Just to let others know.

had that at end.
