Firefox hangs occasionally

Firefox hangs occasionally. Like once every 6~10 minutes. And each hang lasts about 2~5 minutes. When it hangs, it sucks all CPU resource(50%), but the memory cost doesn't quiet change during the hanging. It never crashes. All I have to do is waiting. But it comes a lot and it's killing me.

I hope for some help here, please.
