Recently it seems like the lag on Firefox has gotten significantly worse, even after quitting and restarting. I hate Safari, but it seems to run a little faster. Firefox also takes up more CPU, but I was looking at the activity monitor when opening Facebook and saw the web address for Facebook appear (which I've never noticed before). With the same number of windows open, Firefox takes significantly more memory. Has anyone else noted a recent change in Firefox? Is there a way to reduce the memory storage for it?
