Hello. I wanted to disable this tab group thing that happens when you move tabs around and accidentally hover over another tab with it. So I went to the about:config and toggled browser.tabs.groups.enabled

However, as soon as I restart the browser it resets to true. It doesn't stay false. Does anyone know why?

Thanks.

In recent Firefox versions, the behavior of window.open() has changed. When opening a new window with an empty URL (), Firefox opens a blank tab (about:blank) and then loads the specified content. However, the about:blank tab may not close automatically as it did in earlier versions.

I've carried forward settings from long ago in my profile and I'm trying to figure out what my old settings are that control the scaling of the display. On older displays, I had made a point of using the native resolution for images to avoid blurring, and then changed font sizes to fit. In about:config I've found:

layout.css.devPixelsPerPx=1
layout.css.dpi=144

but copying those to a new profile gives me a tiny display on my higher-res screen. Changing layout.css.devPixelsPerPx works as expected, but layout.css.dpi seems to be a red herring--changing it has no effect in old or new profile. I vaguely remember replacing it with something else after a design change, but I'm not finding it either in about:config or in my userContent.css. It must be something that applies to the page content and not the UI, because my old settings don't affect the menu text and I had to adjust that size in userChrome.css.

(I'm trying to figure this out to diagnose a problem with a web site at work, which doesn't compute the window size correctly with my settings and refuses to display a menu sidebar at my usual window width.)

Is there a way to make the URL high lighting of the domain more obvious? I find that most people can barely see the highlighting and I'd like to make it obvious (bolder and red, or highlighted in yellow, for instance.)

Can this be done via userchrome.css?

Hello,

As it stands, there's an... I dunno, 30 second delay before I can even click the "clear data" button to select that I want to delete my cache.

I wish to remove this. I want to clear my cache when I have an issue that MAKES ME HAVE TO CLEAR MY CACHE. I don't want to wait until Firefox thinks I've understood what will happen EVERY. SINGLE. TIME.

What about:config setting do I have to change so Firefox doesn't treat me like a child who hasn't learned patience?



Thank you.

Hi,

I've been trying to solve this issue for the past several months with no avail. I tried configuring some settings via about:config with:

gfx.webrender.compositor - false widget.windows.window_occlusion_tracking.enabled - false


I also unchecked both "Use hardware acceleration when available" and the "use recommended performance setting".

Essentially, I want to be able to watch movies/videos on sites like Netflix and Hulu. Right now only a black screen shows with the audio playing or the screen is frozen in one scene and the audio continues playing.

Does anyone know what else I can do to solve this problem?

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.

Good day everyone,

I have been breaking my head over this for about a week. After the last update that was installed, now my tab width is smaller than the minimum width I have set them to. However, this only happens with active tabs from pages that have an embedded video. At first I thought this was just a thing with YouTube, but it seems it also happens with other video sites. I guess it may be related to whenever the playback button displays in the tab title and it detects there is video content.

I would like to know how to fix this behavior so that my tabs are no longer shortened beyond the minimum width setting.

Thank you in advance.

I tried the following to add voice search to the Firefox browser in Windows. I followed the instructions in the attached but when I open a new tab voice search is not in the search bar. I returned to about:config and the two settings = true. Why did it not work as it was supposed to?

A new voice tab opened amongst my open tabs and when I select it, it's Google Voice. I then select for personal use, I then have a choice from Android. iOS and Web. I select Web. It then says Google Voice is not available yet in my country (UK).

I use voice search a lot on my Android phone and tablet and would like to use it in Firefox.

I've got full-screen-api.ignore-widgets = true, so that I can use the f11 key effectively as a "hide-the-toolbar" button. this works nicely since I can still use my window manager's fullscreen shortcut to actually go into fullscreen.

the problem is, whenever I do that, firefox detects the change and then shows/hides the toolbar again accordingly. just wondering if there's any way to stop firefox from detecting fullscreen changes?

I naively turned off exit-on windowOpen & windowRaise, but that had no effect.

any help is appreciated.
