Firefox won't open
New Linux user here, installed Bazzite on my laptop yesterday to free myself from Windows 11. It's pretty great but Firefox and Librewolf wont run. Firefox gives me a crash report while Librewolf just loads for a moment and then doesn't open.
Solutions I've tried:
- uninstalling/reinstalling the Firefox flatpak
- disabling Wayland windowing system/enabling fallback to X11 windowing system
- Opening Firefox flatpak from the terminal
- per reddit suggestion: running 'sudo dnf install libcanberra-gtk3' in the terminal
I'm really at a loss for what to do so any help would be appreciated. Attached are the relevant screenshots.

oh and this is the output when I click 'Details' on the Firefox Crash Reporter:
maybe delete the flatpak data
uninstalling firefox doesn't do that automatically
how do I do that?
remove
~/.var/app/org.mozilla.firefox
You can do it in the Warehouse app
cool
under the 'leftover data' tab I assume?
it's such a cool little app
I trashed it, now do I just reinstall firefox and hope it works?
yeah
still not working
strange
weird that I've managed to play balatro on here before being able to open the preinstalled browser lmao
is it possible it's some kind of hardware issue? this laptop is pretty lousy
probably not
i got another idea
installing firefox from flathub
oh thats where I just installed it from
is it?
flathub, in the bazaar right?
i know fedora has it's own flatpak repo
oh wait you're on bazzite
my brain glitched
been using fedora kinoite
ah lol
which comes with only the fedora flatpak repo by default
& fedora's own flatpaks ain't the best
oof
imma install flathub firefox
& see if it works
yeah works for me
let's make 100% sure you are using flathub firefox
uninstall the one you got & run this in the terminal
flatpak install flathub org.mozilla.firefox
will do
same crash pop-up
hmm yeah
this narrows it down
you are using the exact same firefox version as i am
as well as all the exact same libraries that firefox depends on
also this is just a firefox issue (and librewolf but I mean that makes sense as its a fork of firefox). Chrome and Opera work just fine
but I'd really rather not use a chromium browser
there is one thing i can think of which interacts with flatpaks from the host system
& that thing is the input method
search for virtual keyboard in the launcher
& make sure that's set to none
is for me
it was set to maliit so I just turned it to none
same crash
interesting
could this be whats causing the issue?

that seems normal ish
hmm
but i can check on my end
thatd be great
yeah that error is normal
i get it too
ok
here's what i get

this is my full output when I try to run it

what is colorreload-gtk-module?
Not sure! Someone on reddit suggested I run 'sudo dnf install libcanberra-gtk3' in the terminal which ended up giving me the same firefox crash reporter pop-up
it didnt change anything at all either
hmm next idea
what if you make a new user & run firefox from there
does it still crash i wonder
yep
i'm forced to conclude it's something hardware related at this point
still have some ideas though
I'm greatful for any ideas u got
i think it has something to do with colorreload-gtk-module, and maybe your theme?
I tried changing my theme before and it didnt help unfortunately. That said let me go back to the alt user I just made and see if the output is different at all in the terminal
seeing as the alt user is still on the default theme
ooh, good point
so I think the gtk error is related to the theme as it wasnt present in the output there. However the rest of the output was identical and there was still the same crash
i'm currently booted into Nix OS
& flatpak firefox works though i have fedora kinoite dualbooted that also works
imma go reboot into fedora & see if i get the gtk error
just tried changing my theme to one of the defaults on my main user and it still gives me the gtk error
hi from fedora land
hello!
installing the firefox flatpak as apparently kinoite has it installed as a system package
oh wow
the flatpak works with even less warnings on kinoite

just this one
which is expected
thats what happens when I try to run librewolf on this laptop
just that one
and no crash reporter either, it kinda just doesnt open
i got a real silly idea now
what if you were to temporarily rebase to kinoite
That's getting into the territory of stuff I really don't know how to do
I'm brand new to linux
literally installed yesterday
I appreciate all the help y'all but this is getting to a point where its too much to try getting firefox to work on a single pretty awful laptop so I think I'm gonna call it there
ok one last very simple thing to try
install system package firefox
sudo rpm-ostree install firefox
might need to reboot to have it take effect
@antheas i'm being kinda annoying
but this is extraordinary flatpak firefox simply won't launch for OP even on a different user
well the browser won't
crash reporter will i suspect it's hardware somehow but i've used some real garbage hardware & never had this happen
also affects librewolf
