For me, there's been some kind of weird instability or resource leak that resulted in Windows Firefox getting slower all around and less stable the longer the application is running. It's been around and 100% reproducible (over an active session of a few days) for a couple of years.
The general problem used to feature some sort of bug where some window processes would completely fail to render/paint UI components - instead, rendering them as pure black. The rendering problem is gone, same with a correlated memory leak, but the complete performance slowdown that accompanied it is still there.
One day I'll submit a bug report or profiler trace or something, but I find it odd every time I see a post about stability or performance fix, it never happens to be the big one that I run into, regardless of the window device or extensions.
It makes me wonder if some users just have browsing habits that most others don't, so they hit obscure bugs more frequently. But since everyone has their own obscure habits, and thus bugs, there's a theoretical endless deluge of problems with no critical mass to justify prioritization or investigation.
One thing I can say is that it is extremely rare that Firefox actually crashes on me. The instabilities are in the behaviors of the browser, its UI and the tabs/pages themselves. It can slow to a crawl, and even hourglass on me in an extreme case (I usually get fed up and just restart the browser and all the tabs at once to fix the issue before it gets that bad) but it manages to keep itself some, somehow.
That said, I'll poke around in there next time anyways and see if anything stands out. Thanks!
