Wich resources do you find Firefox is using unfairly?
I would say CPU is the biggest resource being hogged. With FF33 running, it's difficult (but not impossible) to open new tabs, run MPlayer, alongside FF. Core i5 (1.6GHz) with 4GB RAM - should it really be taking a hit like that? I usually have a few xfce4-terms open, maybe 4 or 5 FF tabs open, Thunderbird, Mplayer - that's about it.

FF continues to run and shows as the resident CPU hogging process for 2+ minutes even after being closed? @ 300% CPU utilization, even after being closed - nothing being downloaded, normal everyday 4 or 5 tabs open while browsing. Anything else I can report and/or complain about? Not a huge deal since it's not crashing my box, but that resource hogging is just not acceptable.

The offending plug-in/add-on *seems* to be HTTP-Everywhere. Since I've disabled it, FF no longer goes bonkers on my CPU.
