[Bug 884349] [NEW] Firefox crashes/closes when switching desktops

[Red hot smasher]

Public bug reported:

If I start Firefox and switch over to another desktop (using alt-
left/right or the switcher button in unity), Firefox disappears but it's
process remains running in the background. I'm running Unity2D since not
all parts of Unity3D work properly since upgrading from Natty.
