OK so my page file does.
I think I've only given it 100GB or so to play around with, so, sure, if the 32GB of system ram I have available fills up, and all 100GB of my page file get used up, then I'll have to restart FF.
At ~5GB a day of usage, and lets round down for the sake of losses, that is about 20 days of up time before Firefox is denied malloc's by my OS.
Still not great, but a lot better than crashing twice a day!
