What the (Fire)Fox??

I’ve been continuing to use Chrome as my main browser, and so far it hasn’t done anything annoying like upset the Tiggers or spill my coffee. But occasionally I fire up Firefox to test things here or there. Well, a few days back I did just that, and left it running. What I’d forgotten was that I’d had it logged in to an email account. Which is the only explanation I can come up with for what greeted me this morning.

My iMac, normally very quick to respond, seemed very reluctant to show me the password box. When it eventually let me in, it presented me with a box telling my that my startup disk had run out of space for virtual memory. Now Macs can use lots of virtual memory, and generally manage it quite nicely in such a way that you don’t know it’s going on at all. But this was different – when I started Activity Monitor I found the reason. Firefox, having been left alone for a few days[1] was using around 4GB of real memory and a really quite impressive 50GB of virtual. This makes the Safari memory leak I ran into a while back look quite trivial.

I won’t entirely blame Firefox for this one, as I really should have closed that tab, but it is at least interesting that it could manage to use so much…
