Comment 13 for bug 1304351

I removed totem-mozilla over a week ago, and I thought it was helping the first few days. The last few days, however, the issue seems to be returning. It's always after viewing a few YouTube-videos with their HTML5 player that Firefox starts to use over 100% CPU, the temperature of my cores rises to 100 °C and Firefox can only be stopped by killing it (so it continuus to run and use up the CPU when closing the window). After killing the process, the temperature of my cores drops within 10 seconds to around 50-65 degrees.

I'm on the Aurora channel, so I'm running Firefox 33.0a2, on Ubuntu 14.04. Also note I'm running the trusty-proposed channel and everything is up to date.
