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

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.

I use nav bar at bottom and with old menu having reload, back, forward all at the bottom of menu, it meant that I could use Firefox single handedly.

Now with the new menu design which is very nice and shiny (well done), all common actions are on top of menu, close to mid- top of the screen. This makes it hard or awkward to use it worth one hand.

Is it possible, to have the layout of menu adjusted when nav bar is at the bottom?

I hope Mozilla does not add another icon next to the address bar, otherwise it may not be possible to select the address... Do you know a way to edit these icons so they get out of the way? I would't mind disabling translation (not used) or share (accessible via main menu) and the spacing on the icons could use some work too
