Firefox hangs might not be related to the kernel.
It is a known issue that IO can suffer greatly when under high GPU load 
at the same time, and browsers tend to do both at once (hardware 
acceleration and sqlite db for session, cookies, local storage etc.).
That is one of the reasons to use 
https://wiki.archlinux.org/index.php/Profile-sync-daemon and run the 
browser from tmpfs.
The other reason to do this is that the browser feels much faster as 
well :)

Maybe give this a try, it sounds like it might help you.
