nice addon but high cpu usage Rated 1 out of 5 stars

on mac osx 10.7.3 even when not in facebook, cpu usage of firefox with only this addon enabled is 9-10% when idle. vs 0.1 without it enabled...

This review is for a previous version of the add-on ( 

Hey gil levy, I'm aware of that issue, even though this only affects a small number of users. I have, however, no idea what exactly causes the issue as only a few users experience these slowdowns/exceptionally high loads. I've had my add-on checked dozens of times by the Mozilla editors without any issues, but I'm constantly trying to improve stability and user experience. Thank you.
