Is Firefox know to work on arm64?
Just now I tried to build official-stockfish from source to try to reproduce an issue. clang++ crashed so I installed firefox in order to try to log a bug with the attached source and scripts.
First of all firefox failed because one of its shared libraries couldn't load the maths library libm.so. I worked around that with
export LD_PRELOAD=/usr/lib/libm.so
With that it got as far as a core dump.
The core dump isn't much use
Core file '/home/paulf/firefox.core' (aarch64) was loaded.
(lldb) bt
* thread #1, name = 'MainThread', stop reason = signal SIGSEGV
* frame #0: 0x00004820264df434
frame #1: 0x000048202646024c
I tried Valgrind but unfortunately got an unhandled instruction
[NOPARSE]

Fortunately that's a known problem with a patch https://bugs.kde.org/show_bug.cgi?id=392146
Then I tried running firefox under gdb and the GUI opened.
