[SOLVED] Firefox 108.* fails to launch

Hi! After updating to version 108, Firefox fails to launch. There is no output if launched from CLI, and I see no log files produced.

My setup:

Operating System: Arch Linux
KDE Plasma Version: 5.26.4
KDE Frameworks Version: 5.101.0
Qt Version: 5.15.7
Kernel Version: 6.0.12-zen1-1-zen (64-bit)
Graphics Platform: Wayland
Processors: 16 × 11th Gen Intel® Core™ i9-11950H @ 2.60GHz
Memory: 31,1 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics
Manufacturer: Dell Inc.
Product Name: Precision 5560

Also, these env vars are set:

MOZ_USE_XINPUT2=1
MOZ_ENABLE_WAYLAND=1
MOZ_WEBRENDER=1

Unsetting them doesn't solve the issue.

So far, I've rolled it back to 107, which works fine, though I had to downgrade my FF profile.
Any ideas on how to debug this, please?

I opened a bug in the upstream, but it didn't get any response for a week

Was updating FF part of a full upgrade?

Make sure every firefox instance is properly closed before starting the "new" version.

Yes, but later I tried updating only FF (107→108), but it's still the same.

I've rebooted multiple times since then, upgrading and downgrading. The situation is still the same: FF 108 process dies silently after a few seconds.

Re: [SOLVED] Firefox 108.* fails to launch

To eliminate plugins, settings, customizations, try creating a (dummy) new user and run Firefox logged in as that user, which should then be completely 'vanilla'.

Re: [SOLVED] Firefox 108.* fails to launch

I created a new profile and started FF using

firefox --ProfileManager --safe-mode

, but still no luck

Launching it from the command line doesn't produce any output; it just hangs for a couple of seconds and then quits.

strace it.
Does the xwayland backend still work?

I did, but it didn't tell me anything: https://pastebin.com/xAJLFes6

XWayland apps (e.g. spotify) run just fine. However, I don't think FF is using XWayland, since I have MOZ_ENABLE_WAYLAND=1 env set.
Unsetting it and running FF 107 produces a slightly blurry window (probably because I use fractional scaling)

Argh, I completely forgot I have firefox-userchromejs installed from AUR. Removing it fixes the issue.
Hopefully, upstream will solve it soon

Took me a while to realize this myself Updated, now it works. Next time, please flag as out-of-date at AUR, then I get a notification and can update it!
