I-Firefox Isithangami Sokwesekwa

For some reason, randomly, and now this is occurring more and more frequently, Firefox will just hang and say that "Firefox is not responding," and I have to wait ~30 seconds for it to unfreeze and continue using Firefox. I have tried every potential solution that I could find on the Internet, such as disabling hardware acceleration, creating a new places database, etc., and I still keep getting these 30 second freezes on a pretty frequent basis. Do you guys know what might be going on?

I have to go into task manager to stop background processors from freezing my computer. Closing background processors in disk and memory. Sometimes there are as many as 10 background processors running but it seems to be a only a few and can't tell which one's until I figure it out. Sometimes I can by the amount of usage. I have to do this several times as I use my computer.
