Want a Consistent Experience? Simple Steps to Make Firefox Use Windows Theme
Mozilla Firefox typically uses its own interface colors and themes, which can sometimes clash with the look of Windows 10 or Windows 11. By adjusting a few settings, you can make Firefox automatically match your Windows system theme and accent colors for a more unified and visually appealing experience.
Why Enable Native Theme Support in Firefox?
- Firefox adopts your Windows accent color for the title bar and tab bar, replacing its default grey.
- The toolbar color aligns with your Windows theme, creating a consistent look.
- UI elements such as menus, separators, and borders become sharper and more visible.
- All menus and fly-outs use darker, clearer borders for improved readability.
- Changing the Windows accent color in personalization settings will update Firefox’s appearance instantly.
How to Enable Windows Native Theme and Colors in Firefox
Activate System Theme – Auto in Firefox
- Open the main Firefox menu (three horizontal lines at the top right).
- Select “Add-ons and themes.”
- Go to the “Themes” section.
- Ensure “System Theme – Auto” is enabled. If not, click “Enable” next to it.
Adjust Advanced Preference for Native Theme
- Type about:config in the Firefox address bar and press Enter.
- Accept the warning prompt to access advanced settings.
- In the search box, enter theme.native.
- Locate the preference: browser.theme.native-theme.
- Double-click the preference or click the toggle icon to set its value to True.
Reverting to Default Firefox UI
To restore Firefox’s original colors and theme, set browser.theme.native-theme back to False in the about:config page.
This adjustment provides a more cohesive and visually pleasing browsing experience, especially for users who value consistency across their desktop environment.
