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?

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

This button that looks like a jig saw bit will not budge.

Can I delete this in about:config by deleting the 'unified extention button' and can I delete the 'HKLM/SOFTWARE/Wow6432Node/Mozilla/Firefox/Extensions' in the registry?

Firefox these days is getting a burden with more info and such like being collected behind out backs, it's about to be ditched on all my computers, the last few episodes make me want out.

When starting Firefox with a completely new generated profile, I still get following errors in the Browser console tool:

For example (see attachment): services.settings: UnknownError: IndexedDB: main/moz-essential-domain-fallbacks getLastModified() IndexedDB: The operation failed for reasons unrelated to the database itself and not covered by any other error code. Module: RemoteSettingsClient.sys.mjs:555

At this time using Firefox, I haven't configured a Firefox sync-account, to sync settings with the central stored profile on Firefox servers.

Solution: May it is helpful, that if a sync-account isn't configured by a user, these function calls should be suppressed by Firefox, in order to avoid these exception/error messages in Browser console. These error message are just irritating messages, as long as a sync-account isn't configured and activly used.

hello, how to display only the preferences that I have personally modified, without those that an external program has modified: there are too many of them, and this button loses much of its usefulness.

I tried to do this: [quote]Locate and delete the file prefs.js (or rename it, for example, to prefs.jsOLD, to keep the old file as a backup). If you find more than one, a prefs.js.moztmp file or a user.js file,

delete (or rename) these as well. (/quote]

but it doesn't work because there are still “modified preferences” coming from who knows where.

I have tabs that I can see using resources in the about:processes view but the value in the name field is something like "Firefox (8748)" or "https://fooSite.com". If I have a lot of tabs open, which I always do, it's not clear which one is causing the issue. It would be great if there was a way to show the url that is loaded so that one can quickly choose to stop it, reload it, or close it. Yes, the X action sort of let's you do that but you still don't know exactly which tab you are xing and it's only a kill switch for the tab in the end; there's no choice to resolve the issue by just reloading the page in the event of some video element that is consuming gpu for some reason. It might be a tab that I want to keep around. Making a little more meta data available so that a user can easily track down the specific tab would be great. Imagine I have 70 windows open... Yes, probably a corner case but it's the way I roll.

I am just writing to tell you that you can go stick your latest "new and improved" feature (note extreme sarcasm) in AI chatbots where the Sun don't shine.

Someone tell me is Mozilla trying to destroy Firefox?

Are they trying to get people to move to Edge, Chrome, Safari or Opera?

If they are they are going the right way about it!

I am getting sick to the back teeth of Mozilla forcing their crap down our throats.

I have lost count the number of times I have had to go into about:config to turn off the latest crap FX has forced down our throats over the years.

None of us asked for AI Chatbots which is one of the worst ideas ever invented.

I already had to delete Microsoft CoPilot from my PC last September now I had to do it with FX.

Everybody do this and it works:

Goto address bar and type in about:config, goto the search bar and type chat and where it says browser.ml.chat.enabled change from true to false and you will be rid of those garbage chatbots.

I have done that for every forced you you feature FX has added over the years like Pockets and Screengrab and all the other garbage they have added over the years.

Transferring bookmarks & backups for passwords is easy and I'm not worried about that. But the about:config settings that I have customized and accreted over years so that nothing beeps, spins, auto-plays, loops, or throbs a tab, are not so straightforward. I'd like to review what files I can save how to make sure I do not lose these, which are the most important things to me about my Firefox installs--keeping the web safe for quiet, nondistracting searches and reading.
