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, change how buttons look, or make Firefox look like a completely different program.

There are two types of themes available for Firefox:

• Personas - lightweight themes that can change the color scheme and background image of the Firefox toolbars.
  
  
  
  
• Full themes - more customizable than Personas, but larger to download.
