Firefox Nightly build 23.0a1 (2013-05-07).
Latest NVidia Drivers, for my NVidia 670, can't be Ram issues as I've got 24 gig of G.Skill RAM.
Cleared my Cache, cleared my cookies, cleared my registry of faulty entries, virus scanned, all clean. Oh and, AdBlock is off.
This leads me to believe it's the video player at fault.
Anyone have any ideas?
