Firefox for Android Community Forum

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.

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

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

The old menu is more user friendly and everything shows up. Unlike the new menu where you have to search for stuff. Please incorporate an option to choose between menus.

Put back the menu bar!!!!!!!!! Who ever thought it was a good idea to remove it should be fired immediately. Firefox far less user friendly and useful and far less better than other browsers without it!!!! Errol Simpson

I beg you, just add an option to revert. Why, why are you even doing the redesign?? I would happily use your browser forever anyway, please, add an option to revert! I really don't want to move to Chrome, but the new design is so hideous I can't stand it

Many of the changes in the newest Firefox for mobile are an improvement, but one thing that really isn't is the location of the share button. I use this feature more than any other.

It used to be that I could press and hold to select the tabs I wished to share and the share button would pop right up. Now, the menu contains a bookmark icon (star) and a bin. Meanwhile the share button is hidden under the dot menu, even though there's more than enough room for it in the header bar, even with the star and bin.

If there is currently no way to customize the quick-access icons, I encourage developers to consider making the share button more prevalent or allowing users to customize quick access, in future.

Today is February 24th 2026. Sometime today Firefox (Android) just updated itself. Now there's stuff on top, there's stuff on the bottom, (home page, tabs) and I don't care for it very much. How do I go back to the previous version?

A "dead" vertical space appears at the bottom of the viewport, pushing site navigation and sticky banners (like "Get started") upward. This occurs globally across different websites, not just one.

We need to add customization to the bottom panel located under the search bar, as well as the ability to set any wallpaper on the home screen and add a black AMOLED theme for the browser

Hello,

I am using a website with text input fields in a dialog box. When I open the dialog box (show_modal()), I see the entire dialog box (Figure 1). When I type in one of the text fields, it automatically enlarges (Figure 2). How can I prevent this?

Greetings..

hey, have a little issue: it seems i'm not able to change the app icon (android). i've followed the instructions found in https://support.mozilla.org/es/kb/customize-app-icon-firefox-android ; updated the app at the store, rebooted my device and finally (the problem persisted) uninstalled and installed again Firefox app. still nothing, the option does not appear. i'm adding an scrrenshot. very thank you.

So, I noticed that the default font Firefox uses on Android when nothing is specified is a sans-serif font. But I would like to use serif.

I've already seen an answer to change the values of "font.name.sans-serif.x-unicode" and "font.name.sans-serif.x-western" in about:config (also "font.name.sans-serif.x-user-def", but that must have been removed, nothing shows up when I search it), but I haven't gotten it to work. I assume I'm not inputting the right value. What should I set as the value to get it to use a serif font? Or is there another way I should do this?

Hi everyone, I have been using Firefox for only two days, so I am still unfamiliar with some things. I have installed Firefox on my Android mobile phone, and the home page has a shiny orange color that I would like to change to another color. How can I do this?

Thank you for the help
