As title: after running updates, Firefox consistently crashes when launching.
To give more concrete details:
-Running on Linux, specifically KDE Fedora 42. Firefox was updated to 142 from 141, alongside various other updates.
-When launching Firefox from any source (directly, through a link, through the terminal etc.), the only window that appears is the crash reporter.
-This issue occurs when launching in safe mode. Removing and reinstalling Firefox, including deleting the entire .mozilla folder in Home at the same time does not resolve the issue. I am unable to test rolling Firefox back to 141.
-When attempting to launch from the terminal (safe mode or otherwise), the following is output (personal info redacted):
restorecon: SELinux: Could not get canonical path for /home/[username]/.mozilla/firefox/*/gmp-widevinecdm/* restorecon: No such file or directory.
/usr/include/c++/15/array:210: constexpr std::array<_Tp, _Nm>::value_type& std::array<_Tp, _Nm>::operator[](size_type) [with _Tp = HeaderBarButtonType; long unsigned int _Nm = 3; reference = HeaderBarButtonType&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.
Redirecting call to abort() to mozalloc_abort
[ExceptionHandler generates a minidump etc.]
Gtk-Message: [timestamp]: Failed to load module "appmenu-gtk-module"
(I would note that to the best of my knowledge I had not included a plugin for decoding widevine in my Firefox setup, and certainly the Firefox 141 instance on the device being used to write this post (same OS) does not include it)
-The crash files in the .mozilla folder, meanwhile, consistently list a segfault at address 0x0.
Any advice on diagnosing/solving this issue would be greatly appreciated. Let me know if there's any other information that would be helpful.
If it would be more appropriate, I could report this through Mozilla's bugzilla instance, but given the issue seems to be very niche (Fedora's ABRT shows a total of 5 unique affected users in the last few days) I am unsure whether flagging this there would be appropriate.
