My Firefox browser quits unexpectedly several times a week. When I reopen it, I do a session restore and everything works fine. What makes this happen over and over?

Is this with all websites/pages, some, a few?

What were you doing at the time? surfing, watching a clip, reading something . . . .

Does it look like at about the same time? More than once per day?

more options Did you update Firefox to the latest version?

Version 85.0.2, first offered to Release channel users on February 9, 2021

Note that the OP is on Mac OS X 10.11 and can't update beyond Firefox 78 ESR.

Does Firefox crash and offers to send a crash report or does it merely close ?

Are there possibly memory issues that cause the browser to close ?
