Most of the time it’s just Firefox eating about 20% CPU doing nothing else than keeping 30-40 tabs open (found out by trial-and-error it takes more CPU to reload them when clicked (Autounload tab add-on) than it does keeping them loaded (now RAM isn’t too scarce).
For me, I can consistently free up 8 GB of memory by quitting firefox after watching youtube videos and getting a performance decrease. Enabling multi-process mode did not help -- it's not the tabs taking up the memory in my case.
In other words, I can close the window (not just the tab), the memory is still used, I close firefox, and between the drop in real memory and the drop in swapspace, I recover between 7 and 9 GB.
