firefox

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?

My Toshiba laptop specs are:

Ubuntu 12.04 (32 bit)
Linux 3.2.0-30-generic-pae #48-Ubuntu SMP Fri Aug 24 17:14:09 UTC 2012 i686 i686 i386 GNU/Linux
Firefox 15.0.1
Intel® Pentium(R) Dual CPU T3400 @ 2.16GHz × 2
Mobile Intel® GM45 Express Chipset x86/MMX/SSE2

Thanks!

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
