I have two monitors: Monitor 1 is Asus PG248QP(Run in 1920 x 1080 360hz landscape 100% scale) Monitor 2 is G272U Pro(Run in 4320 x 2160 60hz landscape 150% scale). I arrange them veritcally, monitor 2 on top and monitor 1 at the bottom.

When I minimize the non-fullscreen firefox window on the monitor 1, black/transparent border shows on the left, right, and bottom of the firefox window.

When I arrange two monitor horizontally, everything normal. I place monitor 1 at the left of monitor 2.

When I do this on the monitor 2, everything normal.

I have to use two monitors vertically, since I don't have much space.

I also tried different versions of firefox. for now, 129.0 to 136 has these problems. I have install chrome, brave, edge. None of them has this problem.

windows 11 23h2 (22631.5039) cpu: 13900k gpu: 4090 with 572.60 ram: 32gb x 2

Firefox 137.0

already tried refresh firefox profile.

We're attempting to disable either the Firefox Sidebar or the Firefox AI Chatbot via Group Policy, but it appears that Mozilla has not updated their ADMX templates yet to allow this change to be made.

Is this an accurate statement and if so, is there a timeline for when Mozilla plans to implement an update to remediate this issue?

I recently needed to reinstall Firefox to attempt to deal with an issue. It turned out Firefox was not the cause but when the new browser opened, it did not have the Home icon on the toolbar.

I went to "Customize toolbar" and added it but now it shows up on the far right end of the toolbar. It used to be to the left of the URL area. I tried to grab it with the mouse and drag it but it won't move.

Every time I need to jump to a home page I end up going where it used to be. I realize this is small potatoes but is there any way to get it back where it used to be?

The little button, top right of screen, between - and x is not working to reduce the screen window size. I don't like the window opening to cover the entire screen. I cannot access any edges to reduce the window.

Now there is no "other" category for topic of question. This concerns display, layout, and functionality.

Having a huge problem with Firefox recently. It looks and behaves like Microsoft type display, security, and function all around has been superimposed on Firefox. Every time I need to do something online my effort is first redirected to trying to fix configuration problem on Firefox.

It is bad enough to have to do battle with windows 11 to config the layout and display so that it is functional instead of going from one screen to another and another when there is an issues that needs configuring, which always then requires a search and fixing it in Microsoft registry (if possible). Now that is happening with the Firefox display, layout, and functionality which requires a search try to find a page where some kind soul has provided a fix for FF via about:config (if possible).

My brower updated to 136.xx in mid-march after I had already disabled auto update. However, have not had problems until recently, so it seems to be something the microsoft system has started doing to compromise the configured functionality of Firefox. It is no impossible to update or change passwords because "microsoft security" has taken over. Did Microsoft buy controlling interest in Firefox, or what.

Today The layout has started being a problem too. Very elementary without features, with huge words and images although I have changed nothing in Firefox. It is as dumbed down and tedious as Windows 10 when it was brand new. I use a desktop and I really don't want it to look and behave with the limits, and appearnace of a large sized mobile phone screen.

No Firefox update since mid March is showing, however something is interferring with the Firefox display, layout, and functionality. I can only guess it is the Windows 11 OS . . .

Is there a way to protect Firefox from Microsoft meddling with the Firefox configuration?

I have not yet tried to stop enhanced security in each website that is a problem (though most of them currently are, not simply individual websites). Perhaps that is the problem . . . at this problem it needs to be universally disabled if that IS the problem. All the additional security being piled on is simply hoops to jump through for users. We all know it does not stop the pros who are intent on hacking as a team sport. I really do not want to have to fool around signing to a Firefox account, and getting a code to be able to complete the signin to be able configure the brower to simply access the internet.

Starting to think FF, including support, is being managed and responded to by A.I. - which always ends up being a programmer problem that creates the limits. Intentional or not is the question.,,,,

Hoping some kind souls have found solutions, or locations to solutions they are willing to share.

Hello, I've updated my Nvidia graphics driver and encountered this issue. Basically I noticed it on twitch.tv mainly, bottom of my website is hidden behind taskbar, as if firefox thinks I have the automatically hiding taskbar setting enabled, which I never used. I've tried deleting some json file from %appdata% which has not helped, tried reinstalling firefox, running in troubleshoot mode,disabling hardware acceleration and nothing helped. Here are screenshots of how it looks fullscreen and how it should look, as you can see the bottom section is missing. Thanks in advance

Hi,

I'm using FF (128.8.0esr) on Debian testing.

Is there a way to open a site as window w/o any toolbars/menu etc. , preferably from the command-line, some magic switch?

This thread https://tinyurl.com/24b5q2t2 discusses the "ssb" switch but it's not available in this browser.

Thanks

Yesterday morning i had sidebar bookmarks. Then when I turned my desktop back on in the evening it was gone. I have a few "tabs" on top which I do not like at all. I can't find my bookmarks, other than recent ones. How can I get my bookmarks back on the sidebar? I need some sort of fix please, to get my bookmarks back on the sidebar where they were.

There is a black box on the top left corner whenever firefox is maximized. This problem appeared when I got my new computer screen (Asus 27" TUF Gaming VG27AQ1A, 170Hz WQHD). My old computer screen (23.6" VE247H LED, Full HD, 2ms, 10M:1) didn't have this issue.

Any help how to fix this issue?

I have Firefox on two computer (plus my phone), both of them are running Linux Mint. On pc#1 Firefox behaves ok; on pc#2 instead it's abnormally zoomed in and it is very annoying to use. I am logged in with my Mozilla account on both devices, they have the same settings and Firefox is the only application displaying this behavior. If it matters, pc#1 has a bigger screen. I've attached a screenshot of the same page visualized on both devices as to show the difference.

(I am posting this from pc#1)

Yesteday, 4/9/25, I did a Microsoft update on my system. As soon as I opened my browser afterward, all the fonts on the toolbars, tabs, menus, search bar,etc. were changed from the font point they were at, to some miniscule, barely seeable size. This is happening to everything above the work screen in Firefox, and my File Explorer. Everything below the search bar line is as it should be. How do I resize all the toolbars etc. to their previous size? Thank you for any relevant assistance.

I am now wasting precious time trying to figure out how to make the bookmarks and the tabs across the top bigger. Since the auto update, I can barely read the teeny tiny print. How do I make the font sizes something I can read?

I have applied a dark color combined with some managed custom color. Can anyone help me with how I can disable this overriding website appearance by my color selection for certain sites but enable it for all the rest?

When I move the pointer up to a tab, and accidently go to high, this top bar appears on MacOS 15.4.1 - I'm running FireFox 138.0.1 - so I would like to know how to stop this behaviour, and or a plugin or fix to move the close, maximize, minimize button to the left of the tabs, like one Chrome.

I am currently using Firefox Desktop Version for Mac 137.0.1. I tried to use the new vertical side bar instead and even though my browser is in dark mode, the vertical side bar is in light mode. Please, see attached image.
