I recently ran updates and it told me that in order to get those updates I had to update my kernel. I did that and also updated Firefox to 15. Since then Firefox hangs/gray screens sites I go to. This lasts anywhere from 5-10 seconds to 2-3 minutes.
I have restarted Firefox with all add-ons disabled but it still did the same thing. I found a bug report on Launchpad that sounded like what was happening with me, but I haven't received any error codes, just the hanging/frozen screens. Also it seems that it ups my CPU making the rest of Ubuntu lag while Firefox is hung.
I would guess the cause is a conflict between the updated kernel and the updated Firefox, but I'm still fairly new at Ubuntu and not sure where to go from here. Is there anything else to try?
