Frequently Asked Questions

What are Firefox themes?
With Firefox 57 (released in November 2017) Mozilla moves to a new model for themes, based on the WebExtensions standard, that should make it easier for developers to customize the look of Firefox. While complete themes are going away in Firefox 57, Mozilla is beefing up lightweight themes so developers can make their experience richer. Firefox 57 includes a few built-in themes that let you change the look or the browser, including the Firefox dark theme. And you, of course, can add the new lightweight themes to change the look of the browser.
How do I find and add a Firefox theme?
In Firefox, click the menu button over on the right side of the toolbar, select Add-ons, scroll to the bottom of the page, and then click See more add-ons. On Firefox’s add-on page, click the Themes tab to check out available themes, from fashion to nature. To add one, click the link to theme’s page, click Tap to preview on the left, and then if you like the look of it, tap Install Theme on the right. To disable a theme or remove it completely, click the menu button and then select Themes on the left to manage the look of Firefox.
