Please Add Built-in Force Dark Mode for All Web Pages — No Extension Needed

Hi Firefox Android team,

I know Firefox supports the Dark Reader extension, and it works. But I shouldn't need an extension for something this fundamental.

My request is simple: add a built-in force dark mode that applies to every single web page automatically — YouTube, Facebook, news sites, blogs, government pages — everything. No extension, no workaround, just one toggle in Settings that makes every website dark.

The problem with Dark Reader: - Pages visibly blink and flash before going dark - It slows down heavy websites noticeably - It's an extra install that most casual users never discover - It shouldn't be the user's job to find a fix for a missing core feature

Firefox for iOS already has a built-in Night Mode button in the menu. Android users deserve the same — and better. Make it automatic, make it system-wide, and make it respect AMOLED screens for true black backgrounds.

Microsoft Edge and Chrome already have experimental force dark mode. Firefox can do it cleaner, faster, and make it a proper setting instead of a hidden flag.

This is a basic comfort feature in 2026. Please make it happen natively.

Thank you.

Best regards, A Firefox Android user

Isisombulu esikhethiweyo

Hi,

This is a good feature request and many users would agree with it.

Right now Firefox Android only has:

Dark theme (browser UI only) Dark Reader extension for websites

So there is no built-in “force dark mode for all websites” toggle.

Your point is valid because:

Extensions can slow some sites Some pages flash white before turning dark Not all users know or install extensions

A native option would be better, like:

One simple toggle in settings Apply dark mode to all websites automatically With option to turn off for specific sites

This would make browsing more comfortable, especially at night, without needing extra add-ons.

Good suggestion for Mozilla to consider.

Hi,

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or developers. When a Mozilla employee jumps into a discussion, you'll see the Mozilla Staff label next to their name.

If you wish, you can leave feedback for developers on the Mozilla Connect website. Click the Firefox Menu Fx89menuButton button in the toolbar, click Help and select Share ideas and feedback…. Alternatively, you can use this link. Your feedback is collected by a team that reads it and gathers data on the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.
