Slowing down TB Rated 3 out of 5 stars

I have been using this addon for quite a long time and I am very happy about it. However in the past 10 days, I have been experiencing problems: TB hangs upon opening and waking up from sleep, under OS X. TB works perfectly with this app disabled. I am not sure. Too bad, the addon is really useful. Let me know if you need more info.

This review is for a previous version of the add-on (0.16).
