Hello, this morning, i can't use Firefox. I've got an error message on opening : "Firefox is already in use and don't respond. The old process of firefox must be stopped...." And when i click "close firefox", it's opening but i don't have internet.

What i already tried: - disable all plugin - disconnect my firefox profile - run in "maintenance" mode - run an auto repair and clear cache history etc. - uninstall and delete program files folder of firefox - download latest installer and install fresh Firefox - Edit network.dns.ipv6 + network.dns.prefetch

I still have a crash message on startup and no internet. Chrome and Edge are working like a charm.

Any idea? thank you.

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:
