Firefox will no longer load any website, and crashes on quit

My initial problem was that firefox 96 on mac os 12.1 would no longer load any website.

I verified that other browsers work just fine (in fact, i'm writing this on the same machine, but using Chrome).

I uninstalled firefox, and even removed my old profiles. Then did a clean install. The problem persists.

In addition, when I now quit firefox it takes a long time, and pops up the crash reporter every time.

How can I fix this ?

Chosen solution

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".
