Reclaim Vertical UI Space by Adding a Toolbar to the Left or Right Side of Firefox

Do you need to make the most efficient use possible of vertical UI space on your system’s screen, but have horizontal space to spare? Now you can shift the toolbar icons and their awesome functionality to a slim sidebar in Firefox using the Vertical Toolbar extension.

As you can see above the sidebar even picked up on our Personas Theme to help it blend in nicely with the rest of the browser. You can access the options for the new toolbar by right clicking within the toolbar area.

These are the options for the toolbar…you can choose the side of Firefox that works best for toolbar placement, adjust display, hiding, & animation settings, define how the buttons display, and add/remove additional buttons as desired.

Once you open the Customize Toolbar Window make any desired additions or removals just like you would before on the top UI section and close when finished.

Note: Works with Firefox 4.0b7pre – 4.0.*

    @fritz boyle – There was a note right above the download link stating that it only worked with Firefox 4.0b7pre – 4.0.*, but it does not seem to stand out very well so I will change it to bold print.

    I think it’s worth to mention that there’s an extension that optimizes the Firefox user interface to be more suitable to Netbook devices. So basically it gives you more space to surf. It is called Meerkat.

    It’s available here:

    Isn’t this the reason for the new Unity UI? With widescreens, we need to fix the ration; great add-on to make things better. As an aside, the birds were refreshing.

    Thank you AsianAngel for the FireFox feature, it is excellent and optimizes my Widescreen perfectly. I did have to change my Personar to one which allowed the ‘Icon with Text’ to be clearly visible to allow for my aging eyesight, however that was no problem.
    My respects to all at How To Geek for such an excellent and informative site.

    @Stokesley Lad – That is awesome and I am very happy to know that the extension is being so helpful to you. ^_^
