Great Work Rated 5 out of 5 stars
The best Hide Bookmarks add-on xD works flawlessly and it does what it says.
I share the same opinion as other users, could a future version hide the bookmarks bar smoothly? And also the browser window moving up and down when you activate the Bookmarks bar, could it be made so that it overlays the web page? Just a couple of suggestions ;)
Keep it up
