I would like to make the toolbar and bookmark font larger. When I search for answer it keeps telling me to change layout.css.devPixelsPerPx to a larger number. I have done that a couple of times, and after restarting Firefox the font is still the same size. I search the community and didn't see an answer either, so figured I would ask. Thanks Jack

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've pretty much exhausted my simple little mind about this problem. At some point around the beginning of the year, Firefox changed the fonts on all my toolbars to some ridiculously miniscule font. I've queried Google's AI several times, tried every solution I've received, all to no avail. Is there a way to do this? I just want to enlarge the font in all the toolbars, not the web site contents, and lock it in. Thanks to whoever can help me achieve this.

I came to know about Firefox Widgets but can't see any on Firefox 152 on Windows 11 desktop. The option Allow Firefox to improve features, performance and stability between updates is already checked (Screenshot attached) as suggested by users.

Hello,

I am now using firefox widgets and I'd like to know if there's an option to change the background color. They are now dark grey and I would love to be able to costumize them, and choose the color so it goes well with my background and is more visually pleasing to see and use :)

Thank you for your help ! xx

I picked one of the approved Themes; however, after making some moves on the browser, it reverts to the system theme. How do I make the theme I choose stay regardless of the actions that I may take?

In a recent Firefox update, UI was updated to reflect Material Design. However, some elements aren't displaying as intended. However, the screen with tabs is not displayed on the entire screen (that is, it does not extend into safe zones), although the indents on the screen allow this to be done.
