Rated 5 out of 5 stars

So far it's quite interesting, and the only thing I'd like to see in a future version is a somehow noticeable focus on which tab is selected, perhaps with a darker transparency tab selection.

This review is for a previous version of the add-on (1.0.8.1-signed). 

Thanks tribaljet. You can select different tab settings on add-ons preferences page inside add-ons manager. From v1.0.9 on I will switch two settings "default Glass Tabs" <-> "alternative Glass Tabs v3" like Amo-eidtors suggested.

When you install the latest dev version from versionspage or devchannel you will have them already switched. ;-)
