The picture-in-picture setting use to keep the detached video visible if I scrolled the original or source page past the video player. Now the detached video disappears and reverts back to the source page when I scroll this control out of view. Is this change intentional and permanent?

When right-clicking on a tab and choosing Move Tab, the option for a new window has gone MIA from the tab context menu. It still shows To Start and To End. Is there a config option that got changed?

I do not live in Estonia, I don't know estonian, I don't have estonian set as a language anywhere in firefox or any other settings, I don't have any estonian language packs downloaded, the only time I was involved with it was when I accidentally clicked on 'estonian' instead of 'english' when trying to translate a page (once, I clicked on it accidentally once as far as I remember, one single time and no more. Only one time this happened. Once), and it somehow just can not cease asking me to translate pages to estonian, anything that isn't in english, somehow it tolerates that. Actually how does this happen and how do I fix it

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.

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.

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.

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.

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

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.

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 installed Firefox yesterday, and everything was fine for a day. Today, when I play a YouTube video, the entire page freezes - I can't pause it, select text, or do anything. The page starts responding after about 10 seconds from last interaction.

Compared to Chrome, I can play 20 YouTube videos at once and everything works fine.

The problem only occurs on YouTube. Sites like CDA and Jellyfin work fine.

Hi, I noticed that my Firefox version has just been force-updated, on two of my computers, even though I had the automated updates unselected. I also noticed that the new version had added an opt-out option to use "AI" for my tabs which I do not want. There may be other settings that have appeared like this forcing "AI" on me and I am not going to check all of them. I will uninstall Firefox as it is no longer respecting my privacy and autonomy as a user, following the full-blown embrace of "genAI" which goes completely opposite Firefox values such as privacy, ethics, environmental responsibility and respect of their users. I might come back when Firefox goes back to being a privacy and environmentally-friendly browser.

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.

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.

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

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!
