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

I found a UI bug in Firefox for Android on Nothing Phone (1).

Device: Nothing Phone (1) Android version: 15 Firefox version: 150.0.1 (Build #2016157687), 094f3362dcbc efdce34f05b355607cdce06a4ef4 GV: 150.0.1-20260427013024 AS: 150.0.1

Steps to reproduce: 1. Open Firefox on Android. 2. Tap the private browsing icon/tab switcher. 3. Observe the screen layout.

Expected result: The UI should remain stable without moving.

Actual result: The whole interface slightly shifts downward after pressing the private browsing icon.

Lately my Firefox app window will just randomly close while I'm using it. I notice most often on Facebook, but that's because it's the most often used page.

When I reopen the app, it's like I just opened it, not like it got minimized.

What's wrong with it? I have it updated to current version, as well as I've run malware and virus scans to see if it's my phone. Nothing found.

"I am a dedicated open-source supporter who has helped 19 new users switch to Zorin OS and Firefox to ensure their privacy. Recently, on the official Zorin OS forum, I was silenced and threatened with a ban by a 'Community Leader' for defending Firefox's Gecko engine.

They accused me of 'advertising' and 'spamming' simply because I shared how many people I’ve converted to Firefox to show the impact of digital freedom. I am reporting this because it’s discouraging to see major Linux communities treat Firefox supporters as spammers. I hope Mozilla looks into how their advocates are being treated in other OS ecosystems."
