Equivalent diff for tor-browser. I did see a SIGSEGV after a bit of
scrolling around (with swrast_dri.so in the backtrace) and have had
network stop working after using it for a bit until ifconfig axen0
down/up (even local pings didn't respond) - I've seen that before
with older Firefox, but haven't run into it with 130.0.1 - but mostly
seems to be working.

Less important for release I think, but it is tested.

The current firefox-esr version (128.2.0) is working without patches
on M2.
