More Viewable Space Rated 5 out of 5 stars
This add-on allows more customization and viewable space while using Firefox. If you move the orange Firefox button to your tab bar, you will gain approximately 1/4 inch more in viewable space. If you are using a laptop, you need this, since viewable space is at a premium. Very useful add-on.This review is for a previous version of the add-on (184.108.40.206-signed.1-signed).
