Firefox hangs for a second or two every 5 or so seconds

So a few days ago, Firefox just starts hanging/freezing quickly for a second, every few seconds, if it's open for a while. Thing is, I only have it open for 20 minutes or so and it starts, and I've hardly done anything like opening new tabs or none of that. And I notice Firefox's memory on Norton starts at about 250,000 kb when first opened, but then within a few minutes is up to 650,000 kb. Why's it doing this? I haven't done anything to Firefox to cause this problem, and I have no addons/extensions whatsoever, other than Favicon restorer and the Norton toolbar. So why is Firefox hanging every few seconds?
