Can you add a configuration setting to Mozilla Firefox to disable Create New Profile, configurable in the policies.json file? (A second option but a much uglier one would be to disable being able to select a file location for a new profile. Then you could make the default profile directory write only, which would also accomplish the same thing.) (A third option would be to able to configure extensions by default upon installation in the ExtensionSettings policy.)

To explain, I use LeechblockNG on Firefox on Ubuntu. Very helpful. By placing a policies.json file (see at bottom) in /etc/firefox/policies/ directory, I can create a system wide policy. I can make the LeechblockNG extension mandatory and to be installed upon every new profile creation. That all works very well. HOWEVER, there is NO way to be able to set those options in the new profile. So LeechblockNG is installed with default options (which are no blocking at all), which effectively bypasses the addon.

I am also writing the author of the leechblock extension to see if there is any way to set the options for leechblock upon installation (the third option above).

But I know other people have this same question, and at present, if I am correct, there is no way to block new profile creation, or the Profile Manager window in Firefox.

So could you please add that option to the Firefox policies.json configuration? Something like "DisableNewProfiles": true would do it.

Thanks!

My current policies.json file in /etc/firefox/policies/ directory: { "policies": { "BlockAboutConfig": true, "BlockAboutProfiles": true, "PrivateBrowsingModeAvailability": 1, "DisableSafeMode": true, "ExtensionSettings":{ "*": { "installation_mode": "blocked", "blocked_install_message": "Prohibited install more extensions." }, "leechblockng@proginosko.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/4374316/leechblock_ng-1.6.6.xpi" } } } }

I get what looks like a DoS attack every day at 7:43. It disables my PC for about 10 minutes. I have traced it a Mozilla task using the task scheduler. The scheduler provides the following information:

The Background Update task checks for updates to Firefox when Firefox is not running. This task is installed automatically by Firefox, and is reinstalled when Firefox runs. To disable this task, update the browser settings or the Firefox enterprise policy setting “BackgroundAppUpdate”.

I have gone into settings but can't find the BackgroundAppUpdate setting to see if disabling this task will solve the problem. Any idea where it is?

I am having Sync issues. Computer 1 (Macbook Air 2011) and Computer 2 (Macbook Air 2015) were synced just fine. Yesterday I bought Computer 3 (Macbook Air 2024) and when I downloaded firefox onto Computer 3 the bookmarks looked like things associated with me at some point they were not mirroring Computers 1 and 2. I did forget my password so went to Computer 1 which was the first to create my firefox account and reset my password. I then made sure I was logged in on all 3 computers. Computer 2 then decided to mirror/sync to the new Computer 3 losing all my bookmarks instead of Computer 3 mirroring Computers 2 and 1. Computer 1 stayed just fine with the bookmarks I want so I disabled sync on Computer 1 to not lose all the bookmarks. I can see that because Computer 1 is old Firefox is up to date but on a different version running 78.15.0es. Computers 2 and 3 are running 133.0.3.

I am hoping someone has info on how I can get my original bookmarks from Computer 1 back onto Computer 2 and 3

Any and all help is much appreciated

I've been using FireFox to login to nytimes.com for many years. Recently, the nytimes.com website hasn't been working properly. It works fine using Edge.

Symptoms are: (1) The zoom level at login and the zoom on going from page to page is very inconsistent. (2) Clicking the Account button does not open the account settings page. Instead it causes the screen background to become grey.

I restarted FireFox in troubleshooting mode, but this did not improve the behavior. I have a single extension (Adblock). Disabling Adblock on nytimes.com also did not improve things.

im trying to reach a site that is HTTP only and when i enter the address it jumps to HTTPS and then the site says unavailable. ive changed the settings and it still keeps doing the same thing

opening links. I tried opening multiple links, when i'm trying to open a repo on a website. the page is not responding. i have to right click and open it in a new tab. If there is any issue please resolve it. Thank you.

Hello,

I have been using Firefox for many years, but I encountered a problem several months ago. I searched the same window a lot, then closed it. Since then, I have not found anything. It’s impossible to get rid of it and the more I try, the more backups of this window are made on my icon in the taskbar. I currently have 12 displayed with 46 tabs for each one. Can you tell me how to delete them? I thought about uninstalling Firefox, but that would mean losing both my bookmarks and saved passwords. I thank you very much for your help and wish you a very happy New Year. Jean-Pierre

Allow a option to not display recent bookmarks on the bookmarks manager display.

I don't want the recent bookmarks listed in the bookmarks menu. The bookmarks are in sub folders that I easily access I don't want all users to see the bookmarks I created in a history style display in the recent bookmarks menu. It appears I can delete the bookmark from the recent display, but that also deletes the actual bookmark.

A help page on Amazon claims Firefox can play Amazon Prime videos, yet I got a pop-up window at the beginning of the movie (not the TV series) "Downton Abbey," which I purchased in 2022, saying my browser doesn't support HD because of content. That's a paraphrase of a window that flashed on the screen and disappeared before I could take a screenshot. The window linked to a page that said Firefox browser CAN play Amazon Prime videos. So the window makes no sense to me.

Does Firefox support HD videos overall? Is there some restriction for content (whatever Amazon means by that)?

Insert picture in email text does not work. When attempting to drag/insert picture into email text, the message "The following files couldn't be attached: filename.jpg. Please try again later." appears. Firefox 133.03 64-bit is up to date on Windows 10. I have not been able to find a solution. The dragged/inserted picture always ends up outside the email text box and cannot be moved into it. What is a solution? Is this something new or do I need to reload Firefox?

It worked last Christmas!!! It is not important now that the holiday is over but would like to fix it.

I'm trying to switch firefox dev edition to english

There is no dev-edition version in dnf, snap or flatpack, so i simply installed it by hands (from src i guess). But browser is not in english and i don't know how to switch it back. Everything i found related to "lang" is translations and "preferred language to display pages", there is no "browser lang" or smth

Perhaps i can replace some files somewhere in src?
