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.

OS: Linux Mint 22.1 Xia base: Ubuntu 24.04 noble Firefox: mint-001 -. 1.0 / 137.0.2 (64-bit)

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.

Windows 10 Enterprise, managed by my organization, but with just enough admin privileges to customize my Firefox.

I want to disable caching because it seems to cause some webpages and plugins to malfunction, not updating until a manual refresh occurs. The usual method of editing…

browser.cache.disk.enable

browser.cache.memory.enable

browser.cache.check_doc_frequency

…does not work.

Toggle Cache plugin had no effect and threw a “cannot edit data on this page” error.

Please, help.

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.

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.

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?

Thanks,

Thane

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)

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?
