Unresponsive Firefox Ubuntu 12.04

[Nick fragoulis]

Usually after long uptime and some heavy usage Firefox becomes unresponsive and/or temporarily freezes. This is happening with every firefox version since installation. I've verified by both enabling and disabling the other 3 addons i use which are Adblock Plus, NoScript and Ubuntu Firefox Modifications(default).In safe mode everything works fine, in any case Unity global menubar extension for Firefox and Thunderbird seems to be the culprit. Reseting firefox only fix this for few days. I've also verified this both in my home pc and 5 work pc's

This is exactly the same behavior I'm experiencing since I upgraded to 12.04 and my actions were exactly the same - disabled addons, run in safe mode, reset Firefox, etc. Still having issues and find myself surfing with my tablet instead of dealing with the constant hang-ups and/or freezes that I'm currently experiencing on my main pc.
