Comment 374 for bug 993187

In addition to the suggestion in #328, I also disabled java script in FF 13. Edit- Preferences- Content. I always have done a similar tweak with windows & I did it in Ubuntu just out of habit. No freezes under moderate usage for almost 2 weeks now!
I doubt this matters but I created 4 partitions when I last did my last fresh install - boot - swap- 2 file system. Then the kernel roll back.
(I had been using 2 partitions with the "standard PAE kernel" ) and had many freezes.
Thanks Stehem, I am about to dual boot win 7 and 12.04 on a modern 64 bit system, your tip will come in handy! =)
