i don't know why my firefox started multiprocessing all of a sudden, but i've got it back off, now.
i purchased this laptop, refurbished, in mid-2009. it's a model from 2006. it runs, and technically with multiple cores, but it can't handle multiple instances of firefox that want to take multiple gb of ram at the same time. that's just going to make the machine unusable.
i will not be connecting expensive hardware to the internet in the future. i will be keeping all desktops completely offline. when this laptop machine eventually dies, i'll replace it with something cheap from a pawn shop and use it as a sacrificial offering of an access point.
the internet is simply not safe and there's nothing anybody can do about it except avoid taking nice things into it.
anyways. back to what i'm doing..
