Firefox is the third most web browser in the world today. The browser offers many impressive features; one among the many is a dark theme on Mac. Though Mac users like to use Safari dark mode, I have noticed that they have to enable develop menu in macOS. On Firefox, you can enable dark them without using develop tab on Mac.

If you are not using Firefox, you can download the browser using this link. Once Firefox is on your Mac, you can follow a simple method to enable Firefox dark mode on Mac.

How to Enable Dark Mode Theme in Firefox on Mac

Step #1. Launch Firefox on your Mac.

Step #2. Next, click on the hamburger icon from the top right corner.

Step #3. A menu will drop down; select Customize.

Step #4. Now, click on the Themes button given at the bottom.

Step #5. A new list will open up: My Themes and Recommended. You need to click on Dark under My Themes and then click on the Done button from the bottom right corner.

You can see quick effects on your Firefox browser; backgrounds, toolbars, and tabs will become dark immediately.

Get More Themes…

Firefox doesn’t stop to surprise you just by offering Dark theme. You can explore more themes available on the browser.

While you are there in Customization area, click on the Themes button and then click Get More Themes from the list that opens up.

You can change the appearance of your browser by exploring hundreds of themes categorized under different categories viz. Abstract, Causes, Fashion, Film & TV, Holiday, Music, Sports, and more. Click on your choice of theme and then press Install Theme button.

Once a theme is installed, click on that hamburger icon again and click on Add-Ons, and install the theme.

Want to get rid of the theme? Go back to Customize → Themes → Manage, and remove the theme.
