Dear Maintainer,

there is a nasty crash in firefox from version 90, that makes it almost
unusable at least for me. It happens on more pages randomly, but I could
best reproduce it by going on a chatguesser map
(eg. http://chatguesser.com/map/nuujaka) and zooming in several times
with a wheel.

This crash is already noted upstream:

https://bugzilla.mozilla.org/show_bug.cgi?id=1719232

But when I tried to bisect it with the mozregression tool, I couldn't
reproduce the bug with mozilla's nightlies. So there must be something
in the Debian build process which at least facilitates the emergence of
the crashes.

The crash happens on i386, not on amd64. It also crashes on OS X.

Could you help with that, please?

Regards
