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

Why is there in about:config no reference to documentation of the displayed settings?

e.g. browser.chrome.toolbar_tips.hide_on_keydown

What is it? What is the meaning of the values? What is the default value? Why do we have to guess?

It is probably documented somewhere (I hope). Why is there no reference to it in about:config?

Hello!

I would like to dump Chrome and return to using Firefox. I just would like to know if it's possible somehow to remove about:mozilla page from within a browser (it's important for me). If anyone knows of a way to do it - please let me know.

Thank you!

I need to block domain in my Firefox. Lets say example.com. Better if via about:config

Extentions is not a solution (sorry, I cannot comment this for privacy reasons)

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?

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.

Steps to reproduce- (1) Enable 'accessibility.blockautorefresh' in 'about:config' (This is said to ask for permission before redirecting) (2) Go here (3) End up here without permission

Extensions I'm using- Privacy Badger, uBlock origin, clearURLs and Show/hide passwords

Another question, does enabling this setting also stop internal redirection?

new Date(1743623960000).toLocaleString(['en-ES'])

outputs "4/2/2025, 7:59:20 PM" in normal firefox and "2/4/2025, 7:59:20 PM" in Firefox Developer. Test on MacOS and Ubuntu.

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,

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> <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)) ) --- ---

Hello,

I have an issue where, when I switch tabs with Ctrl+Tab, my mouse cursor accidentally triggers something if it happens to be in the center. This is very annoying. I tried Googling how to turn off tab visualization through the config, but it hasn't worked so far.

   * browser.ctrlTab.previews

• browser.tabs.closeWindowWithLastTab
• browser.tabs.animate
• toolkit.cosmeticAnimations.enabled

So now, the only option I see is to turn off Recent Tabs, but then the browser becomes unusable. I also tried the same on a new clean user profile and even on new Mozilla-based browsers, but still nothing. It would be ideal to make the cursor inactive while switching tabs, like it is in Arc Browser and probably many others. But I would be happy enough to just turn off tab switching visualization.

Steps to recreate:

1. Open any website
2. Make any css changes. These will be shown in the Changes tab in the dev tools
3. Close dev tools, then re-open. Now those changes won't be shown

Sometimes I need to close dev tools in order to see how the web page would look normally.
