Hi. I have followed the instructions on the Mozilla site above however this does not work. The Enterprise Roots keep reloading after a while.

Any idea how to stop this happening?

I have read many articles on this but nothing works. The E Roots will in initially not reload but eventually after a day or three its back.

Many thanks

Hi!

I am seeing the message in the subject line having completely removed all trace of snapd and installed Firefox deb under Ubuntu 24.04 using the ppa https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu

about:support says "User Namespaces false — This feature is not allowed by your system. This can restrict security features of Firefox"

The page shown following the link does not help as it just assumes I have installed from a tarball - not the case.

Any idea whats going on?

I am using the plasma DE having installed kde-plasma-desktop if that's of any consequence.

Thanks for looking

When accessing about:logins, Firefox prompts for system authentication (Primary password or master password). However, if the user cancels the prompt twice, the password manager still opens and displays all saved logins without authentication.

This behavior bypasses the intended security check and could pose a risk, especially in shared or public machines

Hello, Until recently, I was able to double tap the browser bar and have the window expand to fill the screen just short of "full screen" mode so I could still see the menu/task bar. I remember I did need to adjust settings for this somewhere but can no longer figure it out now that it is not functioning to this spec any more.

I did check about:config to see if "apz.allow_double_tap_zooming" was set to TRUE and it is, by following this suggestion below:

Hello,

I have old 15 year old mac el capitan -10.11.r with outdated firefox 78.15.0esr 64-bit.... in perfect condition. Unfortunately I can not make updates on browser anymore. Online banking websites does not allow me to use this outdated browser. Would you be so kind to make even paid update for me? Or at least let me know what settings I should change under about:config

Waiting to hear from you! [edited email from public]

I understand that in previous versions, there was a preference in about:config that would let me adjust the delay in ms that I would need to hover over a tab until its tab preview is shown. This preference is supposedly located at browser.tabs.cardPreview.delayMs but when I searched for it in about:config it did not show me any results. Any Google searches do not point me in the right direction either. Does anyone know what I could do to adjust this delay anyways?

Attached is an example of the tab preview I'm talking about.

It seems like every week I've somehow muted the audio in a tab. I think this started a few months ago, but I can't remember seeing any sort of an "upgrade" alerting me to this new functionality. How do I get rid of it?? It's driving me nuts. I search google for a solution, and it's horrible AI search just refers me to an ancient thread that does not work.

Btw, I just saw an announcement by Mozilla about modernizing itself. How about getting rid of the crazy About:Config and making it easier for users to make changes?

Hello,

as per description I noticed that firefox version 138 requires an ArrayBuffer as the argument of WebAssembly.compile() and doesn't allow anymore (like in 137) a SharedArrayBuffer, is this intended or it will be fixed in the future? Follows a simple test case. Kind reagards.

--- index.html --- <title>Example</title> <script> let instance = undefined; async function loadWasm() { try { const response = await fetch('./sum.wasm'); const buffer = await response.arrayBuffer(); const sharedBuffer = new SharedArrayBuffer(buffer.byteLength); const tmpView = new Uint8Array(sharedBuffer); tmpView.set(new Uint8Array(buffer)); const module = await WebAssembly.compile(sharedBuffer); instance = await WebAssembly.instantiate(module); } catch (error) { alert(`failed to compile in wasm: ${error.message}`); } } loadWasm(); function testWasm() { if (instance) alert(`sum 1 + 2 = ${instance.exports.add(1, 2)}`); else alert('invalid instance, failed to compile'); } </script> <button onclick="testWasm()">Press to run wasm function (sum)</button> --- ---

--- sum.wat --- (to convert into .wasm using: wat2wasm sum.wat -o sum.wasm) (module (func $add (param $lhs i32) (param $rhs i32) (result i32) local.get $lhs local.get $rhs i32.add) (export "add" (func $add)) ) --- ---

I have tried every support advice I can find and no matter what I do passwords are not restoring. Here is what I have done: Opened about:profiles Opened profile folder Exit firefox transfer key4.db and signons.jstor files from backup to the new folder

Nothing happens.

I have tried creating new folders and following those steps. I have tried everything.

Is there a way to fully disable HDR support in the latest Firefox (138.0.1)? I use it on Linux/Gnome (wayland) where even though HDR support is disabled system-wide (gdctl confirms that) as well as on the monitor, Firefox insists on displaying YouTube videos in HDR resulting in washed out colors.

Looking into the issue I found that disabling the config flag layout.css.video-dynamic-range.allows-high seems to disable HDR but I'm not sure if this is the appropriate way or if there is another switch I currently don't know.

Any help is welcome!

I had to restart firefox but when i did it reset all my settings. I tried to increase the zoom through about:config but it does not work anymore. I've tried both ways below-nothing works/changes. Please help, it is extremely difficult to read my toolbar. This should just be a simple setting, ugggh.

Way 1. To zoom the whole browser. This will change more than the tabs.

   Open about:config

   Search for layout.css.devPixelsPerPx

   Change the value Slightly, such as 1 to 1.1 or more. The larger the value is, the bigger the contents are. Be careful, this may zoom in or out too much to see the viewport.

Way 2. To change the font size only of specific parts. This would be harder but safer.

   Open about:config

   Search for toolkit.legacyUserProfileCustomizations.stylesheets and toggle it to true.

   Go to about:profiles

   Find your profile's Root Directory and click Open Directory.

   In your profile directory, create a folder called chrome

   Open the chrome directory, and create a text file named userChrome.css

   Put the text below into the userChrome.css file

Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

Hello We have used about:config / app.update.url to change an internal webserver http://<internalserver/firefox This webserver is an IIS server with the latest Firefox EXE (<strong>Firefox_Setup_138.0.exe) on it. It has directory browsing enable and we have confirmed we can see and download the file OK. However, when we perform Help / About, you see Firefox Checking for updates... but then says Failed to check for updates. What are we doing wrong? Where can I check for errors? Thanks

Please for the love of God, get rid of the asinine Show All when opening about:config. It was a stupid unnecessary change (IF IT AIN'T BROKE DON'T FIX IT) and your users have been bitching about it since it was implemented.

I have to manually change the layout.css.devPixelsPerPx setting evertime I switch from my laptop to an external monitor. What can I do to avoid this every single time?

I have bookmarks for the application Obsidian, which uses the obsidian:// protocol, registered in Windows. I type the bookmark keyword, it opens the protocol, and asks to confirm whether I not want to open it.

While I wish I could get rid of the entire dialog, I understand that's a security risk, and I understand that the manual delay is ALSO a security detail (to prevent errant or intentional mis-clicks by malicious websites), I want to disable it.

I'm aware there's a lot of hidden configuration options, but I can't even find the name of what this dialog is called. Every search I have for it yields unrelated results. "Open with" is the only idea I have now, so maybe I should start searching for what the integration or protocol is called within Windows. Maybe that'll put me on the right track.

So, can I disable OR 'configure the confirmation dialog, either altogether OR the delay?
