What is causing Firefox to jump to the top of the CPU cycles list every few seconds? With many tabs open videos were freezing for a second or so because of it, so I closed all tabs and FF still does it jumps to the top of the list. The video freeze is much less, but still perceptible.

How can I best debug this?

Hi fogyreef,

Have you looked at the Firefox Performance troubleshooting section? There is a lot of good information in there that should help to resolve your issue.

Hopefully this helps!
