Firefox for Android Community Forum

I am using Firefox for Android to run YouTube as a Progressive Web App (PWA). As shown in the attached screenshot 1000011880.jpg, there is a persistent red banner at the bottom of the screen displaying "YouTube" and "m.youtube.com". This banner takes up valuable screen real estate, distracts from the content, and ruins the "app-like" experience that PWAs are designed to provide. Request: Is there a setting to disable or auto-hide this bottom security/identity bar? If not, please consider this a formal request/bug report to allow users to hide this UI element once the site identity has been verified, similar to how other mobile browsers handle PWA manifests. I have also attached 1000011881.jpg to show the context of this support request.

Ever since I updated my Firefox for Android app to the latest version there have been these odd grey bars at the top and bottom of the app. It's as if the browser is assuming my phone is shorter than it actually is and is leaving these huge margins (I've attached an image to show what I mean). Firefox is the only app that has had this issue and it persists on every single page. It's even worse if I rotate to landscape as it makes about a third of the screen this grey void. In case it helps solve this issue my phone is a 2024 moto g power 5G.

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.

The issue is visible in the attached screenshots.

Whenever you go from regular tabs to your private ones, or private to regular tabs, the top and bottom margins both grow by about the width of the URL bar. Rotating the phone sideways actually makes it worse, adding bars on the side in addition to the top and bottom ones. The bottom bar will go above the keyboard when you're typing, and so far the only way to get rid of it is restarting the app. It's been affecting me for about a month now; I've attached some examples of how it looks before and after below, and here's some more info about my phone:

Firefox Version: 150.0.1 (Build #2016157687) OS: Android 15 Model: moto g stylus 5G - 2024 Extensions: uBlock Origin

Why do you have a leave feedback button in the app but it leads to the question section instead of leaving feedback options. Lastly, why is it so hard to make Firefox display in dark mode across every webpage?

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

Device: Xiaomi K80 Pro Firefox Version: 150 and 150.0.1 (both affected)

Steps to Reproduce: 1. Open Firefox on Xiaomi K80 Pro 2. Enter Private Browsing mode 3. Observe the top toolbar/tab bar

Actual Result: The top tab bar shifts downward (drops) when entering Private Browsing. The issue persists even after returning to normal browsing mode.

Expected Result: The toolbar should remain in its normal position without any visual displacement.

Workaround: Restarting Firefox temporarily restores the toolbar to its correct position.

Additional Notes: Issue is consistently reproducible across both versions 150 and 150.0.1.

Hi I am using Firefox for Android version 150.0.1 on Android 15. I am facing UI misalignment issues continuously. UI always drops down or goes up (whitespace on top) on every toggle between normal and private modes.

Please check attached step by step numbered screenshots and let me know if there is any possible fix.

I'm using a IQOO NEO 7 PRO 5G, Android version: 15 and Funtouch OS 15. Firefox Version 150.0.1 (Build #2016157687), GV: 150.0.1-20260427013024 AS: 150.0.1 OS: Android 15 . I was having this problem from the previous version (150.0.0).

I know I will probably have to live with that (nonsense) new UI. But how to at least disable UI animations, so that the new menu appears immediately when I open it? I have reduced animations enabled in Android settings but firefox doesn't honor it.

I have set my phone to switch between light and dark mode on schedule. Everytime it does so, Firefox doesn't theme refresh correctly. Usually, the search bar will be on the old theme and I'll need to close Firefox as an active app and restart it to refresh correctly. This also means websites looking for theme refresh signals from the browser do not pick it up correctly and thus the browsing experience is visually jarring. This issue has been around for more than a year. Reinstalling Firefox hasn't helped. This is a bug in the browser code and can be reproduced on my Android tablet as well.

Since we are most likely stuck with the new UI, can we please have a few option add to make it more usable to top bar users? 1) Have the menu attached to the top of the screen instead of bottom, so the back/forward/share/refresh are on the same level as the menu button as before. 2) Option to move History/bookmarks/downloads/passwords to above the bookmark page button under the back/forward/share/refresh line for easier reach when hitting the menu button. 3) The old tab screen could be swiped down to close, the new can't, please add a close X where the tab button is or allow for swiping down again to close the tab page.

Could you make a shortcut to switch on between "dark mode" and "bright mode" in the mobile app browser + pc desktop browser?

There are enough webpages that don't show correctly in dark mode. It is not convenient to change the dark mode each time in settings!

Thank you

Hello,

I am a long-time Firefox user. I am writing to express my frustration with a specific change introduced in Firefox for Android 149.

First, I want to be clear: the new main menu redesign is a good decision. Moving the core controls to the bottom of the screen, within thumb reach, is the right ergonomic approach, and I appreciate that work.

My complaint is specifically about the new tab tray layout.

In version 149, the Normal/Private/Synced tab selector has been moved to the top of the screen in direct contradiction with the philosophy behind the rest of the redesign. This makes one-handed use significantly harder, requiring an uncomfortable reach. The previous design kept these controls at the bottom, which was ergonomically correct.

I had previously managed to revert this change by removing the 'Android UI Redesign' study under Data Collection settings. Since version 149 has baked the new tab tray in permanently, with the Secret Settings toggles also removed, I am left with no option to restore the previous behavior.

I genuinely want to keep using Firefox it remains my browser of choice. However, if no layout option is added in a future update to restore bottom-positioned tab selector controls, I will be forced to switch to an alternative browser. Not out of spite, but simply because the current layout makes daily one-handed browsing genuinely uncomfortable.

I hope this feedback reaches the Firefox Android product team.

Thank you.

I made the mistake of updating a working version of Firefox for Android and once again I had settings forced upon me. The Settings menu on the bottoms is horrible to navigate and I absolutely do not want nor need it. Apparently now I can't access the secret menu to fix it to the old side view for settings. Is there a way to change this? I'm at the point of frustration.
