You can check, which tab/window eats up your cpu. open a new tab and enter:

Now, this is a wonderful addition! I wanted it for ages.
It tells me that there is an amazon tab that is taking 9% of the CPU.
It lacks some features, though. For example one button to jump to it. When You have a hundred tabs open, finding a particular one becomes "difficult".
You can close or reload the tab from "about:performance". One would also want a button to "freeze" a tab. Leave it open, but deny it to update.
It could also pinpoint which components of that page are the worst. Perhaps a video, a banner... and allow to stop it. Or filter it out for ever.
I use a adblocker not especially to block ads. It makes most websites faster, because - loading ads from overloaded ad-farms - flash - javascript monsters - video - .... slows down some websites so heavily that it is no fun to surf there. Try it, and feel the speedup!
