[Bug 881016] [NEW] Computer running very "choppy" since the last update.

[WLB]

Public bug reported:

Since the last update, my computer has been running very sluggish.
There is a delay when I type, pages don't scroll, pages are taking
longer to load, links click and open right away, and the processor
sounds like it's racing.  There is sometimes a delay when switching
between windows.
