Are people getting so many FF crashes? Mine rarely does. I leave it running, opening and closing tabs, for weeks on end.

Same, been using it for over 20 years and probably only a handful of crashes in that time. But I mostly look at dead simple web stuff (like hn) and run aggressive ad blocking so I might not be representative of the average user

I run FF on Mac laptop, Windows/Linux laptop, and Windows desktop and can’t remember it crashing in years.

Naively, the more stable a piece of software is, the more likely that its failures can be attributed to hardware error.

It really depends on what you're doing with your hardware. Overclocking, overheating, unstable power supply, and things like that increase the likelihood of memory bitflips.

Slack caused frequent FF crashes, until I realized Slack has (had?) a live leak. Added an extension which force-reloads the Slack page every 15 minutes and that stopped the crashing.

The only browser I’ve crashed in the last decade is mobile safari, and that’s probably because it runs out of memory

Months in my case. But I have ECC. Every five years I build a new development workstation and I always have ECC.

Does "Weeks on end" = 4? Or do you not take the latest update every 4 weeks?

Its pretty stable for me, except it has some memory leaks. Generally I gotta leave heavy pages open for days at a time to notice, but if I don't close it entirely for over a week or two it will start to chug and crash.

How many DRM-heavy websites do you use? Widevine is a buggy thing.

macOS crashes more than Firefox for me.

Yes
