The video will pause completely unless you are moving the mouse on firefox 32x.

The video stutters/jitters frequently with the use of Nightly 64x.

Youtube with html5 works fine for me on 37.0a1 (2014-12-09) Win 7, e10s ON.

Please check if the issue occurs using Firefox in safe mode (with your addons disabled):

Resolving incomplete - we would need information about what sites it is happening on.

This happens quite on lot on vimeo.com in my experience.
The video keeps switching between play and pause, sometimes even with buffered content available
