Okay, so Firefox 12 is a lot better at memory and CPU usage a lot of the time. And okay, I probably have an excessive number of tabs open. But I’m sick and tired of its CPU usage commonly and suddenly flaring up to 170% (giving me that lovely beach ball), sometimes when all I do is switch windows/tabs! I should probably close quite a few of these tabs, but it’s really starting to annoy me, especially when sometimes the tabs I switch to have nothing on it (that I can tell) that’s memory-intensive!
Okay, vent over. (As an aside, though, I hear that the new FF version has some annoying things to it; I think I may wait on upgrading…)
