1067135 - [e10s] Firefox' content process is eating all my battery

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

With e10s enabled, the Firefox content process is eating all my battery. It doesn't start out that way but seems to get worse over time. I tried using the Gecko Profiler to find out what it's doing but it didn't seem to cover the content process?

i'm noticing an exaggerated VRAM usage which leads the GPU's temperature to jump to 66 degrees> Fan spin at 100% > battery longevity decreases

NB: Nothing is running in the background except for (ProceXP, Eset Smart Security, TresorIT, Truecrypt)

Environment: W8.1-64bit, Core2Duo P8600 @2.4GHZ, GT 9700M with 512 VRAm (with 420 tabs open only 28MB of VRAM is left here!)

Something similar mostly but not purely e10s related. 
GPU fan running most of the time and temperature increase. Hit on battery life.

Tim, does this still happen for you with a current Nightly build?
