Steps to reproduce the problem:
1. use browser for an unspecified time 
2. open multiple tabs
3. roll over one of the tabs, intending to switch tabs

What is the expected behavior?
rolling over tab should highlight the tab, clicking should switch window to highlighted tab

What went wrong?
after using browser for a non-specific amount of time, with multiple tabs in the browser window, I use the trackpad to roll over a tab. Once I roll over the tab, the system freezes, then crashes and reboots from the same point.

Did this work before? Yes 59
