Firefox sometimes doesn't launch after update

Hello.
Recently (around a week ago) I have noticed that Firefox sometimes doesn't load. Like no logs in terminal, no errors, other applications work fine.
That's quite annoying - rebooting system 1-2 times to get browser working.
How could I find what's causing that? I'm using wayland compositor if that's useful.

As always... We all need logs, please.

What's terminal outputting when Firefox fails?

$ firefox

As I said, there are no logs at all with just this command.

Maybe some cache problems?

- Try: using the private switch will always start Firefox normally?

$ firefox -private

- Or clear Firefox's cache.

Maybe extensions problems?
- Launch Firefox with a new / empty Profile.

Re: Firefox sometimes doesn't launch after update

Running firefox -private didn't work, sadly (launched only once). Aswell neither clearing cache, deleting extensions and/or profiles didn't work for me. I'm afraid I can't even access profile manager.

Maybe I could start firefox in debug mode (or something similar)?

Re: Firefox sometimes doesn't launch after update

When "firefox" silently fails, are there indications of a present FF process?

ps aux | grep firefox

?

Does

firefox -safe-mode

work?

Re: Firefox sometimes doesn't launch after update

Sorry if I'm not responding often, this seems to happen only when I don't touch my laptop for a while.

Troubleshooting mode doesn't change anything, firefox still doesn't start sometimes, though proccess shows up (output of ps aux | grep firefox):

Re: Firefox sometimes doesn't launch after update

So FF /does/ start, the processes are also not dormant.
You probably just don't see any windows what brings us to

wayland compositor

1. *what* "wayland compositor" (gnome, plasma, sway, …)?
2. do you get the same behavior on an X11 session?

Re: Firefox sometimes doesn't launch after update

I'm using Hyprland as my daily driver and sway for some other purposes. Both are affected.
And yes, when I again catched this bug, I've exited from wayland session, logged into i3wm (X11) and it launched fine.

Re: Firefox sometimes doesn't launch after update

You'll probably have to monitor the X11 situation a bit longer, but if it's the FF window showing up on wayland (as the process runs), are you running FF/wayland natively or through xwayland?

And does it matter?

Re: Firefox sometimes doesn't launch after update

I'm pretty sure Hyprland sets this as default and starting sway with MOZ_ENABLE_WAYLAND=1 makes no difference. And yeah, I've used Xorg for a while, FF always starts without any issues.
Also I'm pretty sure *it didn't* happen before, like before I updated kernel to 6.0 and some other packages. Maybe I could get some logs to have any clue.

Re: Firefox sometimes doesn't launch after update

First and foremost inspect your pacman log around when the issue emerged to see what you updated.
I suspect the answer will be "firefox"?

I don't really think that this is a kernel issue.
However, if so it'll likely refer to the GPU driver being broken and with it your GL setup?

eglinfo | grep -i -B2 -A16 "EGL vendor"

Can you

MOZ_ENABLE_WAYLAND=0 firefox
