After upgrading to Fedora 37, Firefox will not start

I upgraded Fedora 36 to Fedora 37 using GNOME Software. Now when I click the Firefox icon on the Activities page the cursor spins for a little while then nothing. Looking at the list of process I see:

[dhunter@hp-xs6600 ~]$ ps -ef | grep firefox
dhunter 2534 1681 0 11:06 ? 00:00:01 /usr/lib64/firefox/firefox
dhunter 2540 1518 0 11:06 ? 00:00:00 /usr/libexec/cgroupify app-gnome-firefox-2534.scope
dhunter 2562 2534 0 11:06 ? 00:00:00 /usr/lib64/firefox/firefox
dhunter 2572 2562 0 11:06 ? 00:00:00 /usr/lib64/firefox/firefox
dhunter 2742 2645 0 11:10 pts/0 00:00:00 grep --color=auto firefox
[dhunter@hp-xs6600 ~]$

There’s another thread with a similar story. Maybe it helps?

Don’t tell anybody, but I installed Google Chrome in order to ask this question. Thanks for your tip. It does sound like similar problem. I do not get any error notification but I do get warned about process still running when I shutdown or restart Fedora.

I’m having the same issue, Icecat- a Firefox fork a few versions behind I think- works fine.

can you check the output of:

and cat /etc/hosts


hello, try it:

dnf remove firefox
dnf upgrade --refresh
dnf install firefox

I’m having same issue. I even re-installed F37 from scratch, and after the default install. Firefox won’t sucessfully start. Creates a few processes, but fails to display. I have to pkill -f firefox to make it stop. So I had to install Chrome to post this message.
Follow those instructions. I needed to install ffmpeg and libva-utils.
Now Firefox works.
