Firefox is running extremely slowly after I ran out of disc space. There's now a couple of Gb free, but Firefox seems to run like a dog (chasing the spinning beachball).
If I have a normal page (this one!) and an empty tag open, switching from this page to the empty one and back takes about 20 seconds! It used to be instant.
Safari's fine. Firefox was fine yesterday. Rest of machine (PB G4 1.5GHz, 1.25Gb memory, OSX 10.4.6), today it's totally useless.
I've re-installed over Firefox. I'm not too keen on removing it as I've a bunch of preferences and extension settings (AdBlock) that I don't want to loose.
