How to install and manage Themes in Firefox

This post covers how to install and manage Themes in Firefox. A theme or color scheme plays a major role in customizing the Firefox browser or some other browser. By default, the Firefox browser provides a light color scheme, a dark color scheme, and a System theme (the default color scheme) that follows Windows OS setting for Firefox menus, windows, and buttons. If you are bored with that, you can change Firefox’s appearance as per your interest using different color schemes. Thousands of themes are available to choose from. You will also be able to enable or disable any color scheme, access saved themes, remove an installed theme from the Firefox browser, etc.

Here, do note that you can’t remove the System theme, light theme, and dark theme that comes pre-installed with Firefox. Only the additional themes that you installed can be removed from the saved list as well as your Firefox browser.

   • An Enabled section that shows the current color scheme applied to your Firefox browser. You can click on that theme to find more information such as author name, last updated, and version number. You can also use the available options which include setting automatic theme updates to On, Off, or Default, Disable the theme, and a three dots icon to Remove that particular theme.

Create a Custom Firefox Theme

If you don’t want to install themes from the Firefox Themes Store, then you can also create a custom Firefox theme of your choice. For this, you need to install a free Firefox Color add-on. Earlier, this add-on was part of experimental features, but now it is available to use directly from the Firefox Add-ons Store.

After installing the add-on, the Firefox Color page will open in a new tab. Here you will see different tabs for Preset themes, Custom colors, Advanced, colors, etc. Use the Custom colors tab and then you can set Tab Highlight Color, Search Text, Background Color, Toolbar Icons and Text, Toolbar Color, Popup Text, etc. As soon as you select an option, a color palette is opened on the right-hand section to help you choose a color of your choice. The selected color is applied in real-time on your browser.

When the theme is ready, you can save it, generate a sharing URL, and also export it in a ZIP file or as an XPI file. Once you are done, you can close the browser and the custom color scheme will remain saved.

A custom theme automatically replaces the installed theme (even if that theme is enabled), but you can always change it as well as remove the Firefox Color add-on anytime.
