> 2. Firefox's tab crash recovery isn't as solid. I use chrome with fully persistent tabs, and its a gigantic pain if I can't re-open them

I normally have 5-50 tabs open (so perhaps on the lower end), but I can't recall the last time I crashed a tab in the last 3 years. I also use persistent/pinned tabs and never noticed issues.

Its not the tabs themselves crashing, its when firefox (or my pc as a whole - I'm a developer and its a frequent occurance) crashes, firefox isn't as good as chrome at remembering what tabs were previously open
