Firefox developer 95.0b6 (64-bit) crashing multiple times a day

This is a recent problem but I didn’t note exactly when it started - sometime in the past 10 days, I think.

I reduced my addons to a bare minimum. Not a fix.

I tried safe mode (all addons, themes, etc., disabled). Within a minute, when I keyed Ctrl+F, it crashed.

I also get frequent Tab crashes, which FF is always able to recover from.

These crashes happen when I’m actively using FF AND when I’m working in a very different problem, so the problem seems not necessarily related to GUI interaction.

A forum search doesn’t reveal anyone else having this problem, but maybe, like me, they’re too busy to report it, or just hoping it gets fixed soon.

Any thoughts, anyone?
