100% cpu on ubuntu 12.04 and firefox 17.0.1

[Dave]

since an update of my system including firefox, global menu integration started take 100% of cpu.

I have tried various things:

1) Disabled All the non standard extensions = No change to the CPU Usage
2) Disabled Flash PlugIns (also updated same time) = No change to CPU Usage
3) Disabled "Global Menu integration 3.6.4) Extension = HOOOA CPU OK !!!

Indeed, that's the solution....
Before that I test Firefox beta without this module and my cpu charge seem OK.
So as you I de-activate modules one by one and finally it's really gobalmenu-extension which procure overload.

I see a big CPU spike on startup of firefox 19.0 with Global Menu integration 3.7.1.
Also, during browsing I sometimes experience full stops of all activity in the browser associated with the CPU spike.

I'll add some more info (sorry for the 2nd post): this is on ubuntu 12.04 LTS.
Disabling the extension definitely helps.

Firefox 21.0 + Global Menu Bar 4.1 -> still using up 100% CPU. mostly on focus change to Firefox. The Bookmarks are unresponsive for a few seconds. Deaktivating Global Menu Bar helps.
