We're exploring adopting a default deny policy for Firefox extensions in our enterprise. However when I tested this by creating a custom policies.json Firefox unexpectedly removed all extensions for me, including the ones I thought I had allow listed. Here is my policies.json but just keeping in the Facebook Container add-on to illustrate:

{

   "policies": {
       "ExtensionSettings": {
           "*": {
               "blocked_install_message": "Only approved Firefox extensions can be installed, please email your request to itdept@example.org",
               "installation_mode": "blocked",
               "allowed_types": ["theme", "dictionary", "locale"]
           },
           "@contain-facebook.xpi": { "installation_mode": "allowed" }
       }
   }

}

What I would like is to to allow pre-approved extensions (including if they already are installed) and all other types of add-on, but remove and prohibit installation of unapproved extensions.

Can anyone assist, please?

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

I found this file on my desktop. File type is Firefox HTML Document. Size 1KB. I've never noticed this before and wonder it I should delete it, move it, or what. Anything to worry about? I haven't opened it.

Thanks for any enlightenment you can offer!

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

When I go to view an already open tab it will sometimes randomly move it to the very end of my tabs all the way to the right. I don't want it to move tabs without my intervention. Clicking on a tab should keep it in place.

This has been an issue for about 2 months now. I'm not sure what's causing it or even if it's entirely a Firefox issue as I have noticed something similar happen in another program with tabs that I use often. It still seems like a Firefox issue in that moving a tab all the way to the end is a very specific task that can't normally be done accidentally.

Is there a way to prevent this from happening or has anyone figured it out?

On Firefox beta for android. I prefer my address bar to show my search URL when searching. Instead it just shows my search terms, so "test" rather than google.com/q=test or something like that. I've tried editing the relevant about: config settings and this worked for a few moments but now doesn't have an effect. Anything I can do about this, as for me this is an essential feature? Cheers

Why have ratings of reviews on Amazon disappeared and how do I restore that feature? I do not see a price tag in the upper righthand corner. I'm running Firefox on a PC w/Windows 10.

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

Firefox keeps crashing and Hanging and I get the error message "gah your tab etc" I have followed the advice for fixing the problem but it keeps coming back Its really annoying when you are trying to do something I'm no computer whiz and I have looked at the crash reports, its just gobble gook to me, I need help to fix the problem.

I have a problem. When watching videos on YouTube, especially in 4K, it starts to freeze, and the loading screen stays on indefinitely. The same thing happens when you fast-forward or rewind the video. Switching the video to 1440p or 1080p helps, but over time, even at 1080p, it starts to freeze. but if I switch back to 4K, everything works fine, but only temporarily or until I fast-forward it.

I can provide browser data files. I'll say right away that I've tried a lot of things, and even everything that ChatGPT recommended didn't help. I tried changing the about:config settings related to the video player and codecs.

The only thing that helped was installing a plugin (h264ify by erkserkserks) that disables av1, and in that case the video works fine, BUT only at 1080p, which doesn't suit me, as I would like to watch videos in high quality.

If I disable hardware acceleration so that videos are rendered on the processor, then everything works fine and everything runs smoothly, except that the processor is loaded at 60%. This may be a solution to the problem, but I would like to figure it out and solve it completely, rather than looking for a compromise.

Motherboard: ASRock B850M Pro-A (BIOS date 02/21/2025, DMI BIOS version 3.20) CPU: AMD Ryzen 5 8400F 6-Core Processor RAM: Crucial CP16G60C36U5B (Crucial 2x16 - 32GB) Video card: NVIDIA GeForce MSI RTX 3080 Ventus 3X OC LHR (MS-V389) (Driver version: 32.0.15.7652, Development date: May 14, 2025, DirectX version: 12 (FL 12.1)) Video card driver 576.52, May 19, 2025 The entire system and browser are installed on an M.2 NVMe CT1000P3PSSD8 SSD (Crucial P3 Plus 1TB PCIe 4.0 x4) (there are also other drives) (2 monitors 1440p) Windows 11 Pro If any data is required, I can provide it. All drivers and everything else are installed in the latest version (unless new ones have been released or it has not updated itself). All Visual C++ and Windows components are installed, I don't think there is a problem with them.

The problem only occurs in the Mozilla browser; there are no problems in any other browsers. I also noticed that on some websites where I watch movies, there is a problem with the video. Unlike YouTube, they load normally, but in dynamic scenes, the image breaks up, similar to the image breakup in games when vertical synchronization is turned off. That is, the video is divided into two parts, and one of them lags behind by a fraction of a second. I tried resetting the browser settings, but it didn't help. Everything works fine on my MacBook and in other browsers and devices, so it's not related to the internet.

Please help me figure this out and solve the problem because I've already tried everything, and I don't want to switch to another browser because I've been using Mozilla for over 15 years. Also, if you need any information or a detailed explanation, I can show you or even record a video. Everything worked fine on Windows 10 on the same system, but Windows 11 is not running as smoothly. (To clarify, this is a clean system; I did a complete clean install of Windows 11, although when I upgraded from 10 to 11, everything seemed to work fine).

I would be grateful for any help.

Hi, the latest nightly version crashes everytime on my Pixel 8 Pro. Clearing cache, force stopping and restarting the phone doesn't help.

version 141.0a1 org.mozilla.fenix

On certain websites , the audio and video still auto play even though the option, "AutoPlay" is blocked for both audio and video.

Please see the attached screenshot which shows that auto play is blocked, it is circled in red. While the video has auto played, circled in orange with a timestamp of 17 seconds being played prior to it being manually stopped.

Please fix this issue.

Once I visit any web site that uses HTTPS there is approximately a 90% chance it'll take seconds or even minutes to secure the connection. This never happens on other browsers as they load such pages instantaneously.

I already cleaned my data up and removed the extensions, both suspected and innocent bystanders, to no avail.

As stated in the title, I'm using Firefox 139.0.1 x64 on Windows 11 (24H2, build 26100.4061). This started happening after an automatic Firefox update, I never changed anything in my system configuration.

I cannot for the life of me figure this out. Whenever I load a website that needs location (for example, Google Maps or my province's lottery) and enable location permissions, the websites come back saying they cannot find my location.

I have refreshed Firefox, disabled all Enhanced Tracking Protection, disabled all extensions, and have even ran Firefox in Troubleshoot mode - all to no avail. Is there any way this can be fixed? These websites all work on Chrome and Edge and work on my Firefox for iPhone.

On Windows 10 22H2.

I'm trying to install Firefox on my work computer (ARM64 version), but when I do I'm getting the crash report window at the end of the installation process (multiple times in a row), if I try to open the browser (only once), and during the uninstallation process (also multiple times in a row). I've tried a clean reinstall multiple times, including deleting the folders from program files, %APPDATA%, and all registry entries I could find (HKEY_CURRENT_USER>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE>>WOW6432Node).

I've contacted IT and they don't seem to think anything pre-installed should be affecting this. I'm unable to get a crash ID as I'm unable to even start the browser - all I get is the Firefox crash reporter, immediately. Is someone able to help me figure out why I can't get this working?

I downloaded the most recent Firefox update (version 139.0.4) and since then, Firefox has been prompting me to restart to continue using Firefox every day. When I give the go ahead to restart, I get a pop up that says I need to either exit the Firefox client completely, or create a new profile to continue using it because Firefox detects an older version (this is even after updating it manually).

It's made about 5 profiles since the 10th, and they're all still in tact. I clicked my very first one and it very much still works (and even gives me a popup when I open it in a new window that says Firefox is using the latest version). It's been really disruptive to my work flow as it has happened several times in the last two days. I keep checking my settings and it says that I'm updated to the latest version of Firefox, but it continues to kick me out.
