Almost there on mac, perfect on win Rated 5 out of 5 stars

It's awesome, but sadly I found a bug on mac 10.7.4 / ff 13. There is a situation in that no tab gets selected, and any double click in an empty area (creating a new tab) results in a flash in the last visible tab, but none appears. In this state I can enter in Tools - Add-ons, the new tab is created and shows up, but the tree doesnt (just the same flash). It seems I can reproduce almost always by restarting firefox with the last tab selected... I also tried disabling all my other add-ons, no change. And tried installing the last version from your site. PLEASE fix this, it's really great!

This review is for a previous version of the add-on (0.14.2012050301.1-signed).
