The last few days, my Firefox has been freezing at random times. The CPU usage shoots up to 50% and it's often consuming 200 MB of memory, which after it begins to freeze, increases at 3-5 MB/s. Has anyone had similar problems? I haven't changed my addons in months. I updated to 3.6 after the problem began, but it didn't change anything. I'm hoping someone has some insight on what's causing this issue, because I'm running out of ideas here.
