[Bug 915496] [NEW] Firefox is freezing and the screen fades in and out like it's crashing. I sometimes don't have a cursor and sometimes nothing happens when I click on links.

[WLB]

Public bug reported:

I turned on my computer today and immediately the screen started fading
out like it was freezing and then coming back up and it did this several
times.  When the update manager appeared on the left side of the screen,
I was not able to click on the manager to see the updates and instead
had to right click on it and click install updates.  I frequently have
problems with a cursor not appearing.  It happens at least three times a
day where I have to either force the computer to shut down using the
power button and when I can, click restart.  I have been having problems
since installing 11.04, but 11.10 is by far the worse.
