The Addon Bar for Firefox 3.2
Functional with Firefox 29 and up, the Add-on Bar for Firefox replaces the old bar with less clutter. The add-on is designed for Firefox users who already have several add-ons installed on their browsers, as well as for long toolbar items. When you get the Add-on bar back, you will also get back your status bar. This means that it can work with a variety of extensions, including Forecastfox Weather and Status-bar Scientific Calculator. If you want to move the status bar around on your display, you can do so.
