Firefox fún Android Community Forum

I have selected 'Dark/Auto' in my customization settings. I assumed this setting was meant strictly for the Firefox app UI theme, not to automatically force dark mode onto web pages. However, the issue now is that websites are being forcibly rendered in dark mode. I actually appreciate forced dark mode because it renders images and colored text cleanly without messing them up. The real problem is that I can't seem to find any option to turn it off. When I try enabling dark mode using a website's own native toggle, it displays inverted/negative colors, whereas light mode works properly. So my question and issue come down to this: how do I disable the feature that automatically forces dark mode on the websites I browse? (I haven't been able to find this setting anywhere.)

Hello!

I would like to report a UI display issue in Firefox for Android, version 153.0.4.

In the tab overview, the bottom bar displays the tracker-blocking information in Russian as “заблокировано 6 трекеров” (“6 trackers blocked”). However, the text does not fit in the available space and partially goes behind the three-dot menu button on the right, so the text is cut off.

I have attached a screenshot showing the issue.

Please check the layout and positioning of the bottom bar elements to ensure that the tracker-blocking text is fully visible and does not overlap with the three-dot button.

Thank you!

I prefer the light mode fire fox browser, as it contrasts with my system's dark mode so I can easily distinguish what I'm looking at. However, Firefox Android's light mode is appearing as black for me. Dark mode works normally, and it's a dark grey. The frustrating thing is yesterday it seemed fine, with light mode being white.

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.

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.

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

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

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?

I’m using Firefox on an Android tablet in PC mode, paired with a keyboard and mouse. To enhance the desktop experience, I’ve switched the tab view from grid to list. However, I can’t enable full-screen mode for the entire app, something I can do on Firefox Desktop. On YouTube, videos automatically switch to full screen when I enter full-screen mode, but this feature seems missing for the browser itself. Maybe the full-screen option isn’t available in the settings.
