Latest update from firefox-esr 68 to 78 broke firefox. It's exiting a few moments after the start, giving channel error, bus error. in gdb following the SIGBUS's brings out a GraphicsCriticalError: |[C0][GFX1-] Receive IPC error abnormal termination.

Errors are in /usr/lib/firefox/libxul.so and /lib/ld-musl-armhf.so.1

Classic application log:

stderr_stdout_firefox.txt

Gdb output in which I tried to continue until it crashes:

stderr_stdout_gdb_firefox.txt
