On the netflix start page, press Ctrl+L then type about:config, accept the warning and search for these vars to change them.
WIth this, the process no longer tries to use other processor cores and the FPS is fine on my Ubuntu 12.04 LTS x64 running on a AMD Phenom II 1090T 6-core processor.

dom.ipc. plugins. enabled = false processCount = 0
dom.ipc.
Leave the others intact.
