Rated 3 out of 5 stars

good add-on. I use FF 4.0 and noticed the following things.
1. Hiding does not not start immediately if i disable the hide delay.
2. The Bookmark toolbar always pops-up when i switch between the tabs. Maybe u can implement a configurable hover location
3. When i enable the CTRL option, the toolbar is always hidden and never appears.

This review is for a previous version of the add-on (1.21.1-signed.1-signed).
