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.

already tried refresh firefox profile.

My bookmarks have been removed from the bookmarks toolbar. I'm not sure how this happened or how to restore them. In the attached screenshot, you can see the bookmarks and their folders still exist under "Bookmarks Toolbar", yet they're gone from the toolbar itself. I'm not sure what to do next?

I used an icon from Customize ToolBar that disappeared and disrupted my work organization. I don't know what it's called. It was on the right side of the Menu Bar next to Library icon and when I needed it I clicked on it to open the List of History/Bookmarks/Other Bookmarks on the left side of the screen. The icon was a square divided into two parts. In addition, the links I saved that I use often under site finder disappeared. Sincerely, S. Vlad

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.

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.

Thanks - from redirected and disenchanted in ABQ

My Firefox toolbar used to show the address box, and at the end of the address box was a search box. After the last update, the search box disappeared and I would like to get it back. I used it constantly because it would hold my search and if I needed to tweak it a bit, it was still there and easy to do. Now I have to type the search in the address box and it goes away immediately. There was also a drop-down that listed my last few searches. The address bar goes almost completely across the page. Is there a way to get my search box back at the end of the address box? Thank you.

If letterboxing (anti-fingerprinting) is used or when a webpage is smaller than the window (such as in about:config), Firefox fills in the rest of the window using a dark gray. I want to make it completely black.

This is what I currently have in my userContent.css

```CSS @-moz-document url-prefix("about"), url-prefix("chrome"){

 body{ background-color: rgb(0 0 0) !important };
 .sticky-container{ background-color: rgb(0 0 0) !important };
 #toolbar{ background-color: rgb(0 0 0) !important };

}@-moz-document url-prefix("about"), url-prefix("chrome"){

 body{ background-color: rgb(0 0 0) !important };
 .sticky-container{ background-color: rgb(0 0 0) !important };
 #toolbar{ background-color: rgb(0 0 0) !important };

} ```

Is there any setting that allows to get rid from this annoying Titlebar (line with buttons) in fullscreen mode? So that it never shows up even when hovering the mouse pointer over the top edge of screen. When it jumps out everything slides down and always leads to miss clicks when I try to select tabs. I don't want it to be constantly present here as well because it takes up screen space.

Last week the bookmarks button to bring on the sidebar disappeared from my toolbar. Browser and OS up to date. In my attempt to add it back I now see it has also been eliminated from the Customize palette. What gives?

I spent a ton of time perfecting my Firefox, making it look exactly how I wanted… but there’s one huge problem. My entire setup relies on userChrome.js, and I haven’t found a way to make it run permanently without pain.

I’m completely out of energy trying to fix this. But maybe someone here knows a proper workaround?

No js loaders and other hacks worked, so I’m sharing the full code. Maybe you can help me figure out a way to keep it running consistently?

Here’s my code:

function fixTabOrientation() {

   let tabbrowserTabs = document.getElementById("tabbrowser-tabs");
   let arrowscrollbox = document.getElementById("tabbrowser-arrowscrollbox");
   let newTabButton = document.getElementById("tabs-newtab-button");
   let peripheryBox = document.getElementById("tabbrowser-arrowscrollbox-periphery");
   let navBar = document.getElementById("nav-bar-customization-target"); 
   let urlBar = document.getElementById("urlbar-container"); // Адресний рядок

   if (tabbrowserTabs?.getAttribute("orient") !== "horizontal") {
       tabbrowserTabs.setAttribute("orient", "horizontal");
   }

   if (arrowscrollbox?.getAttribute("orient") !== "horizontal") {
       arrowscrollbox.setAttribute("orient", "horizontal");
   }

   if (navBar && urlBar && !urlBar.nextSibling?.isSameNode(tabbrowserTabs)) {
       navBar.insertBefore(tabbrowserTabs, urlBar.nextSibling);
   }

   if (newTabButton) {
       newTabButton.style.position = "absolute";
       newTabButton.style.right = "10px"; 
       newTabButton.style.top = "50%"; 
       newTabButton.style.transform = "translateY(-50%)"; 

       if (peripheryBox && !peripheryBox.contains(newTabButton)) {
           peripheryBox.appendChild(newTabButton);
       }

       newTabButton.style.display = "block";  
       newTabButton.style.width = "32px";
       newTabButton.style.height = "32px";
   } else {
       console.log("New Tab");
   }

}

fixTabOrientation(); setInterval(fixTabOrientation, 1000);

Any work solutions would be massively appreciated—I’m honestly exhausted fighting this.

When I am browsing the web I want the display to be full screen width. I don't want split screens. I don't want a permanent left column, like Zen appears to have. Can I toggle (hide/show) that left column ? No one appears to use analysts any more (we were expensive) The young programmers that are used instead, love dreaming up (and implementing) design changes, just because they can.

As you can see from the image, the bookmark sidebar width can be expanded, but the width of the text portion does not grow with it. My longer bookmark names get truncated. Is there a setting to deal with this? If so, how do I access it?
