firefox segmentation fault

[chrisvollorenew]

Hello, I am trying to run firefox headless and I get a segmentation fault with not much more info.

root@r16-renew-vista-e:~# firefox -headless --safe-mode localhost
*** You are running in headless mode.
Segmentation fault
root@r16-renew-vist

Here's some info about firefox and my system:

root@r16-renew-vista-e:~# firefox --version
Mozilla Firefox 68.9.0esr
root@r16-renew-vista-e:~# uname -a
Linux r16-renew-vista-e 5.17.0-rc8 #1 SMP Thu May 4 23:20:23 UTC 2023 armv7l armv7l armv7l GNU/Linux

I ran a strace to get more info with strace firefox -headless --safe-mode localhost 2> strace.out strace.log

The last lines show:

Please help!

I noticed the firefox recipe has not been updated in a year ... maybe that has something to do with the issue here. Is firefox not well supported here?

[OldManYellsAtCloud]

If interested, I have a fork with a more up to date Firefox (though I can't offer an awful lot more support than you get here). You can find it here: https://github.com/OldManYellsAtCloud/meta-browser

Regarding strace, it could be more readable if you could run something like strace -s 500 -ff -o /tmp/fflog -v -y firefox -headless --safe-mode localhost - this will create a bunch of files in /tmp folder, one for each thread.

If desired, a PR would be nice :-)

@OldManYellsAtCloud you could maintain firefox here, so we avoid the fork

[chrisvollorenew]

Thank you @OldManYellsAtCloud - it am very interested in Firefox 116 because if it’s support for v4l2 (as I understand earlier versions dropped support for v4l2 and gstreamer) - do you plan to bump to version 116 when it is released?

[OldManYellsAtCloud]

@otavio - will try to get back on this topic during the week. Principally I would be quite interested in that. @chrisvollorenew - Firefox is currently at version 117, and I have updated my repo a few days ago to this version. (In the commit history you can also find v116, if that would be better for whatever reason).
