Diễn đàn hỗ trợ Firefox

I have asked this question once before, but was hoping I could get some help by asking again. The text on my screen will completely bug out, and I have no idea how to stop it. I will attach several images from this screen alone showcasing the issue. It occurs everywhere, including captions. Only Firefox has this issue on my computer. I have tried refreshing Firefox once, and it did not solve the problem.

Dear sir or madam,

Can you please help me with a deeply frustrating problem I'm having with Firefox? After the last update, the shortcuts on my FF homepage disappeared and I can't restore or rebuild them.

Under settings, the homepage is set to show two rows of shortcuts but none are visible. I changed it to show more rows, closed & restarted FF, but no shortcuts appear. I then changed it to no rows, closed & restarted FF, then set it back to two rows, closed & restarted FF - still no rows. I've tried starting FF in troubleshoot mode, but to no avail. Looking through the Community Forums, I can't find anything that directly relates to my problem. In case this may help, I've had this problem once or twice before but I'm afraid I can't remember how it was resolved or if it was anything I stumbled upon that fixed it.

The environment is FF version 136.0.2 (64-bit) on an Acer Aspire E5 PC running Windows 10 Home, 64-bit, version 22H2, last updated 16 March 2025.

If you can offer any suggestion how I can resolve this and stop me pulling my hair out (in my case, it's an endangered species!), my remaining hair and I will be eternally grateful.

Yours faithfully, Peter Palmer

I am running with ubuntu 22.04.5 (linux)

I am trying to reduce the width of a panel which is on, say, firefox home. I can easily change the height of a panel (just put the mouse on the edge of the corner or top of the panel. However, when I put the mouse on the edge of either side of the panel nothing happens. I want to reduce the width of a panel and I cannot. Should add that the mouse turns into a resizing thing for all panel - it just doesn't work when trying to change width)

Thoughts?

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.

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.

Hello, I have an empty space on the toolbar between the "New Tab" button and the "Minimize Window" button in Firefox. Is there a way to remove or reduce this space to make better use of the available space? Any help would be appreciated! Thanks.

Bought a new monitor which is set to 3840 x 2160 by default, so i had to change the Windows UI display setting to 200% for my eyes.

This is fantastic on Windows and works as expected with Chrome and Edge browsers. Type appears to be correctly anti-aliased. It does not work with firefox, however. Both the browser UI and viewport content is pixelated.

Attached are three examples of the pixelation on text that we are seeing.

There is no scaling set within the browser - this is a new install with everything set to default at 100%.

Is there a system setting that we need to invoke in order to smooth type within the viewport. There are several articles on this forum that seem to touch on type smoothing but we were looking to confirm whether there is a default setting that can be changed outright.

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?

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.

Is there a way to show bookmarks on particular sites without showing them all the time?

My use case is that I have a plugin's url set as my home page and new tab page and would like to be able to see my bookmarks when I open a new tab but not when I'm on other tabs.

Bonus question; is there a way to have my new tabs open to that plugin's url but also have the url bar empty for browsing?

Thanks in advance for any help with either of these I imagine specific questions.
