Enable Dark Mode
Firefox uses "themes" to customize the colors of the web browser's user interface. Therefore, there isn't technically any "dark mode" in Firefox, rather we'll just be changing to a dark theme.
Follow along with the step by step instructions below to enable the dark theme in your Firefox installation.
- Start by opening Firefox, clicking the menu icon (three stacked lines in the upper right corner), and selecting Add-ons.
- Click on Themes on the left side of this window, and scroll down partially to see the dark theme. You can enable it by clicking the enable button next to it.
- These same instructions can be used for re-enabling the default theme, selecting a different preloaded theme, or even building your own theme with custom colors and the Firefox Colors add-on.
That's all there is to it. The changes will be instantly applied and you can resume your browsing activities as normal. If you have Firefox Sync enabled, your installations of Firefox on other devices will also reflect the new change.
In this guide, we saw how to enable dark mode/theme in Firefox on a Linux system. Dark mode is easier on the eyes, and many users just think that it looks better. Whatever your preferences are for colors, Firefox makes it a breeze to change them.
