Do you think your menu bar takes up too much of your browsing room in Firefox? Over the years, not a lot of changes have happened to the menu bar that your find on top of most applications. Your File, Edit, View choices always seem to stay the same. What if we could shrink Firefox’s menu bar down to one drop down menu? That would save some space, right?
After you install, right click on any toolbar and choose customize. Drag all items in the navigation toolbar (back/forward, address bar, etc) up into the menu bar. Right click on a toolbar again, and un-select the (now empty) navigation bar. Tada, tiny!
