Firefox Community Forum

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.

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

Bonjour, je ne peux plus me connecter à ma boite mail hotmail.com depuis la version 144.0.2 (64bits) de Firefox Je suis avec Windows 11 famille 64 bits - 24H2 et 25H2 (j'ai essayé avec les 2 versions) avec un compte local. Je choisis de me connecter avec un mot de passe et après avoir validé le mot de passe, j'arrive sur une page qui me dit d'utiliser un autre appareil ou une autre méthode de connexion. Je joins les fenêtres de connexion étape par étape Avec Google Chrome (que je ne veux pas utiliser), je me connecte sans problème à ma boite mail avec les même étapes décrites ci-dessus. Pouvez-vous m'apporter une solution ? Merci, Marc T.

Youtube does not work. It shows somekind of default page that is essentially blank. It does say: "Try searching to get started" and "Start watching videos to help us build a feed of videos you'll love."

But it will not respond when I attempt to search anything.

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.

I am having difficulty using Google Sheets within Firefox Developer Edition 144.0b4 (64-bit) on Linux Mint 22.2 Cinnamon. When I load any of my Google Sheets, I am unable to scroll. This includes when using a blank sheet.

I also have Firefox 143.0.1, which seems to still be functioning correctly.

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

Since the last update, the firefox taskbar icon is showing a strange shopping card icon? How can I remove it? I am not shopping with Firefox, I am using it as my web browser.

ZIMBRA sous FIREFOX semble ne pas supporter les mails au format HTML Problème quand je fait suivre (forward) ou quand je réponds à un mail rédigé en HTML. Je n'ai pas ce problème quand j'utilise ZIMBRA sous EDGE. Est-ce un problème connu ? Est-ce une question de réglage ? J'utilise bien la dernière version de FIREFOX...

Help !

Just noticed this starting yesterday. Possibly it started when Ffox updated to v144.0 and I just didn't notice immediately.

I use the address bar (location bar, awesome bar) for searching (with Google, per settings). Up until very recently, the result of hitting Enter after entering my search string would be the URL for the Google results. This can be very handy to copy; e.g., when offering citations during an online discussion.

However, I don't see the URL anymore. After pressing Enter, my original search string remains there, in the address bar. That's not what I want. Using Google means my original search string is right there at the top of the page, in an input field, that can be made active with a single keystroke. Therefore, if it is intended to be helpful by keep the contents of the address bar what they were before I pressed Enter, may I just say that it is not.

Note: I can get the old desired behavior by going to google[.]com and entering the search string there, but that's an annoyance, after years of being able to simply hit Ctrl-L.

Attached is a screenshot of what I now see. Note what's in the address bar -- my original search string. Previously, it would have been something like "https://www.google.com/search?q=this+is+a+test&sca_esv=[ ...]"

All of a sudden I cannot log into my amazon.com account on firefox??? This does not happen with Chrome or Safari. When I try logging in firefox freezes and I have to quit the application and restart.

Moderator note: This question has been edited to clarify the subject.

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.

Running Windows 11. Receiving notifications from Firefox that indicate system warnings and viruses found. I have run several scans using Norton and there are no viruses. This notification is enticing me to click to remove the errors, which seems to clearly be a phishing scam, but I have never seen this as a notification from my browser as opposed to an email. When I try an option to "disable notifications", Norton blocks it due to it being identified as a dangerous "blacklist URL". I can't find a mozilla setting to block this.

The URL is long but what I can see is the following. via d3nt17anaffc73eqftbg.owx-adguard.pro

Hello, you keep coming up with new and different ways to use Firefox, but you are not able to fix it to where Firefox can be used with too many websites. I am constantly having to use Microsoft Edge to connect to Hulu and The Hartford Ins. Co., just to name two which I use frequently. I don't like it, especially the problem with Hulu, which I use a lot, being retired. There are several other websites with which I have problems when I use Firefox, but can't think of them right now because I use them much less frequently.

I would be eternally grateful if you could get those problems fixed once and for all. Oh yeah, I do contribute do Mozilla once or twice per year.

Thank you, Gabrielle Pine [email address]

"This profile was previously synced to a different account To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using xxx@xxxx.xxx, create a new profile."

So I deleted my old mozilla account since I abandoned the email that it was linked to, but when I tried to sync with my new account I get this. Is there anyway to do this without having to make a new profile?

I tried making a new profile and copy and pasting my profile into the new one, but still get the same pop up. I guess there's something in my profile that says it's been synced before, is there anyway I can find that and delete it or change it?

Earlier I logged in to Firefox to pose a question. Checking email, I had a notice from Mozilla that my account was used to sign in: Firefox on Windows 10 / United States (estimated) / Thursday, Oct 23, 2025.

Does Firefox think I'm using Win 10??? I checked my computer and it verifies that I am running Win 11 with all updates.

Call me confused. Or is this a non-issue? I ask because I'm trying to get into a member website and after I login, it takes me to a page that is for new signers ... not an existing member. Has happened several times.

Thanks,

Ron

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

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.
