Any chance you could provide a backtrace?
I think I have the same issue. It may be the same problem as this comment in the firefox bugtracker (https://bugzilla.mozilla.org/show_bug.cgi?id=1641749#c2) which also has a backtrace. I'm rebuilding firefox with debugging symbols to see if I can get my own backtrace.
I will take a gamble and say that we have the same segfaults with the backtrace i attach. I found the culprit to be "0027-bmo-1618914-Wayland-Fall-back-to-ftruncate-if-posix_.patch". Removing it seems to fix the crashes, minus the problem that the patch supposed to fix. If it's not the case, i'm sorry for the noise.
Are you using ZFS?

Thank you Thomas for finding the offending patch & Luis for testing, I though that Firefox crashing on my wayland setup is some old library which I forgot to update.! Thank you guys!!! (meanwhile compiling like crazy and looking forward to crash-less experince).
