Rated 5 out of 5 stars

Good add-on ! Keep on improving !
advice: have a switch to turn on/off auto-hide feature.
When hidden, the long url in urlbar should be longer, occupying the hidden place of addon bar.When the add on bar displays, you can trim the long url.

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

Many thanks for your review!! I´m working in that features, but i need time, because I have to also update other addons. Again, many thanks!!
