Need more space in your Firefox toolbars and menus? If you want to eliminate some dead space in the browser, then you need the Tabs Always in Titlebar add-on for Firefox. This extension for Firefox will bump your tabs up a level – giving yourself a little more minimalistic view of your default Firefox GUI.
Once you install this restart-less add-on, it will bump your browser tabs up to the same level you see the Firefox button. I have been looking for a simple way to do this since Firefox 4 came out – and now that we are already on Firefox 5 – I am happy to see somebody got around to creating an add-on to meet my needs.
If you are using a netbook, this is an excellent add-on to add because it gives you more room to check out the content you want to see. You can pick up Tabs Always In Titlebar add-on from the Firefox Add-ons website.
