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?
