This tutorial is only intended for Mozilla Firefox users running LinuxMac OS X, macOS Sierra or Windows operating systems.

Mozilla's Firefox browser provides conveniently-placed buttons tied to its most commonly used features in the main toolbar as well as within its main menu, accessible on the far right-hand side of that very toolbar. The ability to open a new window, print the active Web page, view your browsing history, and much more can be achieved with just a couple of mouse clicks.

To build upon this convenience, Firefox allows you to add, remove or rearrange the layout of these buttons as well as show or hide its optional toolbars. In addition to these customization options, you can also apply new themes which transform the entire look and feel of the browser's interface. This tutorial shows you how to customize Firefox's appearance.

First, open your Firefox browser. Next click on the Firefox menu, represented by three horizontal lines and located in the upper right-hand corner of your browser window. When the pop-out menu appears, select the option labeled Customize.

Firefox's customization interface should now be displayed in a new tab. The first section, marked Additional Tools ​and Features, contains several buttons each mapped to a specific feature. These buttons can be dragged and dropped in the main menu, shown to the right, or in one of the toolbars located towards the top of the browser window.

Using the same drag-and-drop technique, you can also remove or rearrange buttons that currently reside in these locations.

Located in the bottom left-hand portion of the screen you'll notice four buttons. They are as follows.

  • Title Bar: Displays Firefox's Title Bar, which is positioned directly above your open tabs and contains the title for the active Web page.
  • Show/Hide Toolbars: Presents a drop-down menu, when selected, that allows you to toggle on and off the display for both Firefox's Menu Bar and Bookmarks Toolbar.
  • Themes: Allows you to select from a group of pre-installed themes as well as choose from hundreds of thousands of others available on Mozilla's site.
  • Restore Defaults: Reverts all customizations that you have made and returns Firefox's look and feel to its original state.

As if all of the above wasn't enough, you can also drag the browser's Search Bar to a new location if you wish.
