Every version of Firefox since, but not including, 113.0.2 has been completely unstable when built on my musl + clang + wayland (no X11, not even xwayland) system. Unfortunately, the last working non-ESR version (113.0.2) has been removed from Portage on July 17th, 2023. :( Most commonly, Firefox fails to start up at all and outputs nothing to stdout/stderr. Sometimes, Firefox fails to start up and reports a segmentation fault: zsh: segmentation fault firefox Rarely, Firefox will briefly start up and allow browsing for a few seconds. It then crashes with output like this (although it doesn't look too helpful): [Parent 27155, IPC I/O Parent] WARNING: process 27295 exited on signal 11: file /var/tmp/portage/www-client/firefox-115.0.2/work/firefox-115.0.2/ipc/chromium/src/base/process_util_posix.cc:264 console.error: ({}) console.error: SessionStore: "The session file is invalid: TypeError: state.windows[0] is undefined" console.error: "Experiment next-generation-accessibility-engine-powering-screen-readers has unknown featureId: accessibilityCache" console.error: "Experiment next-generation-accessibility-engine-powering-screen-readers-and-other-ats-copy has unknown featureId: accessibilityCache" console.error: "Experiment next-generation-accessibility-engine-powering-screen-readers-and-other-ats-copy has unknown featureId: accessibilityCache" Exiting due to channel error.

Reproducible: Always Steps to Reproduce: 1. Launch Firefox. 2. If step 1 succeeds, just browse a bit, it will crash soon enough. Actual Results: Firefox almost always crashes on startup or very shortly after.

Unfortunately that terminal log isn't telling anything. You'd have to most likely compile firefox with +debug and give a full gdb backtrace to get some idea what's wrong. You may find a working patch from https://git.alpinelinux.org/aports/tree/community/firefox (check the log for latest editions, https://git.alpinelinux.org/aports/log/community/firefox ) but that's a shot in the dark until you know what's causing the issue. Maybe the pipewire is related? Do you visit sites playing some sound, are you using pipewire? Maybe that's busted. Any better with -clang? You can also try -system-icu. But again, just guessing here.
I'm rebuilding with the debug USE flag now to see if I can get any extra information; it'll take a while. Firefox is a bit of a beast though, so I don't really know where to start debugging it to get the stack trace or other handy info. Judging by the nature of the crash (inconsistent segfault) I'm doubtful a stack trace will be super helpful as I kinda expect some random memory is getting corrupted and the crash happens later. Looking at the Alpine patches is a good suggestion, but, this was the first thing I did when I found that 114.0 was crashing and I didn't find anything that was obviously useful. I am using Pipewire but the crash happens in a fresh profile without visiting sites with sound. Additionally, on one of the few occasions Firefox kept running for over a minute (very rare), I was successfully able to play a YouTube video before things crashed. If I were to guess, I would bet this goes away if I use -clang mostly because I think Alpine builds with GCC and most Gentoo folks build with GCC, I have no other solid evidence for this theory though. I'll try -clang and -system-icu after I exhaust what can be figured out with debug. If there's any good advice on how to get good crash data using debug, I'd be happy to hear it :) .
Here's what I was able to get out of lldb and the debug USE flag. I'm happy to get any other useful information; just let me know! $ lldb /usr/lib/firefox/firefox (lldb) target create "/usr/lib/firefox/firefox" Current executable set to '/usr/lib/firefox/firefox' (x86_64).

These upstream bugs look related. I'll try to include the patches into 116 which is out next week. You can test them via /etc/portage/patches already of course.
I rebuilt 115.0.2 with the patch you linked and everything is stable again. Thanks for looking in to this and getting this in to the next version!
