Firefox Community Forum

Is there a way for me to opt out of any new "AI" functionality/features that would otherwise be enabled by default? Like the tab suggestions and perplexity in search. Having AI shoved down my throat from every corner of the internet is kind of frustrating.

Hello. I can't access the Western Union website through Modzyl. The site opens on Edge. I disabled all add-ons, the browser tries to open the site and reloads the request constantly. How to solve this problem?

Trying to run Prime and Netflix in a Linux browser on my new Lenovo Chromebook Plus 14. Not that this is an ARM based unit (Kompanio Ultra 910).

I can successfully download Firefox for Linux: Mozilla Firefox Debian Package mozilla-deb-1.0 144.0 (aarch64)

But when I go to run streaming video services get: Prime Video is incompatible with your current operating system or web browser. You must update to watch Prime Video titles. Review the Prime Video system requirements. If the problem continues, please contact Amazon Customer Service and refer to error 7132.

Same with Netflix.

any ideas, thoughts, solutions?  :)

Cheers.

At the top of my settings it says: Information: Your browser is being managed by your organization.

What does this mean? It's my personal laptop, I bought it myself and I don't work for any organization.

Thanks for your help. Nancy

started a new profile, imported bookmarks, the about:config settings won't die. I've deleted the user and prefs.js data etc. but all the dumb changes I made before switching users just make their way back no matter how many new profiles I create. I have standard Firefox, with Nightly and Private versions installed. Win 11 25H2 whatever its called now.. please help.

To sign into Chatgbt I used my google account. Mozilla asks me "do I want to store info in persistent storage?" I click "learn more" about persistent storage. It takes me to a page that has zero mention of the words "persistent storage". That is a huge UX error. It says to me that really, you don't want me to know about persistent storage, and prefer that I remain confused and feel forced to agree to things I may not really want to, because you're making it difficult to understand what's actually involved. Not cool. Definitely now considering changing my browser after over 20 years.

Just what the headline reads, I have had zero problems before but with the new update my browser keeps slowing down and crashing on DuelingBook (a yugioh sim) even though it never did before. I havent tested other sites, but pokemon showdown works still so I wonder what the problem is.

After having upgraded my W11 system to 25H2, I cannot install any extension. Installation terminates with "... something may be broken". I'm using FF 144.0,2. FF is used in more than one account alternatively.

On a second system, with less security measures, I have no problems.

Hello all!

I've started having an issue in the last few days, with apparently two separate Firefox installs. A few days ago I was greeted by a fresh, blank install of Firefox and had to set everything up and sign in as I usually would on a fresh system install. Today, however, I somehow managed to launch both of them at once (I don't know how, as I just use the UI shortcut). After closing both fully, I can now only start the "old" one via the shortcut.

OS: Bluefin / Fedora 42.20, Gnome 48.6

According to the list of flatpaks, only one is installed. Unfortunately that's roughly where my knowledge of Linux ends, so I can't troubleshoot this further. Help will be apprecciated, as I don't want to roll a die on which of these will start up every time I reboot.

I just updated to the most recent Firefox version and read about the unload feature. Sound great, but when I right click on the tab the menu does not have unload as an option.

Recently, when I copy and paste an error message to the search box in Firefox and the first word contains a ':', such as when searching for this error message - "MESA-LOADER: failed to open dri: /usr/lib/x86_64-linux-gnu/gbm/dri_gbm.so: cannot open shared object file" - I get the "Open the mesa-loader link with System Handler?" prompt (see screenshot).

I used to be able to copy and paste such an error before into the search box and it would just work but now the browser defaults to thinking you are entering a URL. This could be because when I start typing in the search box, it immediately relocates what I'm typing to the address bar. Maybe this is the behaviour I need to disable? But how and why is it the default?

Help!

I get a daily email from this site and suddenly nothing. I try to resolve the issue and your security settings are unintelligible. I have received emails on a daily basis for over 2 years, and now nothing.

This is unbelievably frustrating.

Facebook Games - I get this: "Sorry, your browser does not support this feature. Please use a different browser and try again. " What do I do? - 10/20/2025

Hello Mozilla Support Team,

I am writing to report a problem with the Mozilla Firefox browser. After the latest update, the browser appears to no longer decompress content that is compressed using the zstd (Zstandard) algorithm.

Previously, I could view web pages or resources compressed with zstd without issue, but now they fail to display correctly (or give errors). I have tested this on multiple websites and different systems, which suggests the change is not specific to one site or machine.

Could you please clarify the following:

Has support for zstd‐compressed content been removed or disabled in the recent Firefox version?

If so, are there plans to restore this support in a future release?

Is there a workaround or configuration setting that allows enabling zstd decompression in the meantime?

Thank you for your attention to this matter. I appreciate your help in ensuring this functionality is restored or clarified.

Best regards, Oleh Boiko Windiws 10, FF 144.0.2

I had two Firefox windows on my computer, one with a few tabs of Youtube and Twitch pages, and a private window with a single Twitch stream. I've had them and the program open for days, with my conputer turned on and off multiple times with no issues.

Today I booted a game I installed yesterday on my computer and played for a few hours, after closing the game, both my Firefox windows became completely inaccessible.

I've tried closing firefox, restarting my computer, letting Firefox create a new xulstore file and nothing has worked. I can't see the window, I can't make it active. It's permanently minimised.

It spikes Desktops Windows Manager to 100% GPU usage, it makes my PC lag and run slow, and I can't do anything in the browser cause the window won't stay open or up. I can't even open the old window and then a new one, it stays minimised and I can only see the preview by hovering my mouse over it.

I've tried GPU driver updates, I tried anti virus scanning, and I've tried opening another browser which did work. But Firefox is the one with all my saved settings and preferred browser. I also can't see the Firefox window at all when using the window key + TAB to check my desktop, but it does show up on Task Manager as running.

Please help me restore my program. I'm making this on my phones firefox browser which is running fine
