You had extension conflicts all the damn time. There was a utility called Conflict Catcher (https://en.wikipedia.org/wiki/Conflict_Catcher https://en.wikipedia.org/wiki/Conflict_Catcher) that would identify the culprit by doing basically a binary search and turning off half the extensions and rebooting (many times) and noting if there was a crash, and deducing the problem extension that way. It was kind of like "git bisect" before that was a thing. This craziness is no longer necessary. I mean... when you DID get like 20 extensions all running together stably though, it was AWESOME.
