Rated 5 out of 5 stars

I've been using TMT for about a year now. I cannot begin to tell you what a weight has been lifted from my FireFox because of this wonderful addon. No longer is there a huge lag-time caused by all the tabs being 'live' - even when not being used. I would tell anyone who has a lot of tabs - GET this. USE this

This review is for a previous version of the add-on (1.2.0).  This user has a previous review of this add-on.
