Works well and has good options Rated 4 out of 5 stars

This add-on works very well to hide the tabbar to give you more screen space. I like the options it provides to not auto-hide, but instead use your Control or Alt button to get hide the tab bar whenever you want. This is the option I use.

This review is for a previous version of the add-on (2.7.1-signed.1-signed).
