[Bug 1132234] [NEW] Firefox 19 unresponsive for a few seconds if using the globalmenu extension

[Antonio]

Public bug reported:

I'm using firefox 19 with the globalmenu extension. After selecting the
firefox window, the first attempt to interact with the program (i.e.
open or close tab, select a tab, scroll down the webpage etc.) makes the
program unresponsive and the CPU runs at 100% for a few seconds.
Afterwards, the required action is performed and the program works fine
until the focus is moved to another window and back to the firefox
window, then the problem appears again. I've noticed that disabling the
globalmenu extension solves the problem.

I'm on Ubuntu 12.10 with

unity 6.12.0
firefox 19.0
firefox-globalmenu 19.0 (in the firefox add-ons page is described as Global Menu Bar Integration 3.7.1)
