Has never crashed on update for me, at least that I can remember after ten years. I have seen the warning message, that arrived years ago however.

I'll add the caveat that I typically restart my browser at least once a day, perhaps avoids the problem.

It wasn't immediately after update. It was after you updated it while it was running and then you tried something, that triggered the crash (like opening a new tab).

Later it stopped to crash, but acted weirdly (clicks on links didn't work, etc).

Nowadays we have the notice to restart the browser. It didn't arrive years ago, just a few releases ago.

This was only under Linux, and only with the distro package managers. Under Windows or MacOS, the updater updates the browser on next restart, so this didn't happen.

Yep, understand that.

I restart my browser at most once per week and Firefox has never crashed for me after an update. I do not doubt that there was a risk that it could happen, but it cannot have been that common unless I was very lucky.
