Expected results:

I have a 8gb laptop and never had this issue before it was max 300mb/process. Even my game never sucked this much ram before

The issue seems to be with Facebook

Can you provide your list of extensions from about:support? It's possible one of those is causing your issue.

This sounds like a dupe of bug 1379139. Please reopen if you are still seeing this issue with an up to date Nightly.
