Bug Description
I've been seeing UI hangs after switching tabs in Firefox, and switching from other applications to Firefox.
It can take 3-8 seconds to change *tab*. During this time the CPU is maxed out; typical output from 'top' during this period shows 'hud-service' and 'unity-

53 0.6 6:14.86 hud-service
38 1.5 6:42.14 unity-panel-service
I suspect that the change is causing a (an inefficient) re-index related to updated menu structures. (Eg. something like the history menu, although I can't see what it is as don't currently have a menu bar).

Thank you for submitting this bug report. I have not been able to reproduce this bug though. I keep alt-tabbing everyday between firefox and other apps and don't see this behaviour. Firefox does use a hefty 250-300 MB during usage but this is normal. Can you please resubmit this bug report using apport so that we can get a better look at your system info which will help the developers greatly. Until then I am marking this incomplete.
