A theme is a type of Firefox add-on which changes the visual appearance of Firefox. This article describes how to find, install and manage themes in Firefox.

What are themes?

A theme changes how Firefox looks. A theme could simply change the toolbar's background colors or the buttons' appearance, but some themes can make Firefox look like a completely different program.

There are two types of themes available for Firefox:

  • Background themes - lightweight themes that can change the color scheme and background image of the Firefox toolbars.
Themes - Win1
Themes - Win2

  • Complete themes - more customizable than background themes, but larger to download.
Themes - Win3

Note: Complete themes will stop being supported with Firefox 57. For more information, plese see Firefox Add-on Technology is Modernizing and its Frequently Asked Quesions.
