Random CPU Spikes - FPS Drops In Game - Firefox lag

[KKHAN]

I am getting random CPU spikes whilst playing games, it lags a lot and Ive noticed a drop in fps when Firefox is running. Though I have a good system which should be able to handle this.

Can someone please advise and what the think the problem is?
