Netflix stopped working with Firefox saying that an update is required. My Firefox and OS (Win11) are completely up to date.

Since latest upgrade (1/16/2026) I cannot log in to Outlook email. This is specific to Firefox 147.0.1 (Chrome and Pop Peeper logins to Outlook work fine). I tried clearing cache, updating, restarting, rebooting, trouble-shooting mode, private window etc. to no avail. I get 400 error from Outlook.

I'm unable to login to account.apple.com on my laptop which is running Ubuntu 24.04.3 LTS.

I've launched Firefox using the `-p` option, created a new profile and then navigated to https://account.apple.com/sign-in and tried to login. I've attached a screenshot of the error message.

I had tried multiple things on my default profile, even troubleshoot mode, but I couldn't get it. I even tried useragent switcher to no avail.

I can login to the site using Chromium.

What else can I try?

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.

Hello. I am using Linux Mint 21.3 cinnamon and Firefox 144.0.2 When I use Google maps and the yellow small pointer (cartoon) to go on a specific street, the window come black when shifting to street view. My only extension is disabled, hardware acceleration unchecked, cache cleared and cookies cleared. I have made fresh install and nothing help. Troubleshooting mode allow street view to work fine but normal mode don't work. Google chrome work good. Chromium work good. And finally, Firefox work ok on my Linux mint LMDE 6.

Any idea where to go to solve this issue?

Thanks for your support

André

I have emptied cache, reset everything and I still get

Access Denied You don't have permission to access "http://www.cabelas.com/home" on this server.

This is from Cabelas.com but I am getting it more and more from other web sites. American Airlines, Delta.com, etc. I accessed the help and did all the steps about fingerprinting and turning off "enhanced tracking protection" and nothing helps. Any ideas? Don't like the idea of using Chrome or Edge, but Firefox is almost unusable for me now. If I have to keep using another browser for the sites, may as well just use that one only.

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 !

Issue: A regression in Firefox version 142.0 (64-bit) breaks the display of the CAPTCHA widget on the login page for https://my8k.me/login

Evidence: The two attached images provide a clear comparison:

   Image 1 (Firefox 142.0): The CAPTCHA area is completely missing or fails to load, showing only a broken element or empty space.

   Image 2 (Other Browsers / Older Firefox): The CAPTCHA renders correctly and is fully functional, confirming the problem is isolated to the latest Firefox update.

Conclusion: This indicates a specific compatibility bug introduced in Firefox 142.0, rather than a general website or user configuration error.

This has worked for me for years. It just began a few days ago when I tried to login and look at my new auto insurance policy. I've cleared the cache/cookies to no avail. I can access the web site with Edge (yuk)

When signing in to online Shaw Webmail, message says 'Security Check Failed. Clear your browser cache and retry'. Screenshot attached. Have done so in "Clear browsing and data history", (as per Firefox guidelines) multiple times, for all History and cache. Did not resolve issue. Contacted Shaw Support; they instructed to try logging in with Chrome browser. Worked fine. Issue appears to be strictly with Firefox Browser (on multiple devices). I prefer Firefox over Chrome. Any advice greatly appreciated.

I can't watch Twitch live stream and videos after updated.When I watching live stream on Twitch, the stream start showing some old tv effect but in colours green. I thought was Twitch problem, then I changed to watch video from my college by using their website. But it still has that effect. But I can watch Youtube videos with no problems. Then i changed to use Microsoft Edge to watch Twitch, surprisingly with no problem. I already updated to the latest version in Firefox. Can anyone help me Please. Thank You

I'm trying to access Tiermaker but it won't let me because it says it is insecure. On other browsers, however, I can access it fine without any warnings. I don't have any accounts on there or anything that could be at risk. How do I access Tiermaker?

When I log into my Outlook Web account, after putting in username and password, it sends me a verification number to my phone. When I put that number it the screen says "Logging out of Microsoft Outlook" and then takes me to the logged out screen. This was working fine until the last update of Firefox, and it works fine in the Duck Duck Go browser. It also works on my Android Cell phone.

Still getting this error after page refresh on O'Reilley Auto Parts and a few other sites when searching. (I don't get this error when on O'Reilley com home page, but ONLY when searching for a part on O'Reilley and ONLY with Firefox on my desktop. This started just a few months ago. All ad blocks and U Block Origin are disabled). I don't get this error with Google Chrome on this Windows 7 PC or on my Android phone. Any help is appreciated. Thanks.

When I play YouTube videos in Firefox, the video stutters and drops frames, even when set to 480p. The audio continues to play normally. This issue does not happen in Chrome on the same laptop.

The problem started about a week ago. I’m using Firefox on Windows 11. Restarting Firefox did not resolve the issue. I’ve attached screenshots for reference.

Hello After last firefox update this page mail.proton.me (specifically: https://mail.proton.me/u/0/inbox) does not load for me.

It works in chrome and edge but not firefox. I cleared my cookies and cache but it did not help. All I get is blank white page and sometimes error message. I attach screen from my F12 menu when I try to load page. In brave for example there is much more activity than in FF.

When I try to log in to my account with Amazon Prime, Firefox freezes as soon as I hit the Continue button after entering the username and password. I can't open or close tabs or do anything. I don't have this problem with the Amazon account in any other browser.

Any ideas why this happens and how to fix it?

I can no longer access my local TrueNAS server nor router via Firefox. My current version is 133.0.3. Safari has no trouble. Firefox gives no warning, no Advanced button, no option to bypass security. All I get is: "Unable to connect An error occurred during a connection to 192.168.0.102.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."

I have tried so many settings, troubleshootings, workarounds, I can't begin to list them. It happens in troubleshooting mode. I have created SSL certificates on the server many different ways to no avail. I'm thinking I will have to abandon Firefox with it's obscure, no-way-through security. But I wanted to ask for help first. Please help.

Problem started with Firefox 146.0.1 Windows 11

1. Open outlook.com in FF browser (https://outlook.live.com/mail/0/). 2. Open any email. 3. No side scrollbar appears so you can't page down within email. Note: the Outlook folder scrollbar does appear and does work. 4. The within-email-item side scroll bar does appear from outlook.com opened in Edge browser. So this is a Firefox bug.

Have tried: a. Windows settings->Accessibility->Visual effects->Always show scrollbars = on b. Turned Adblock on and off for outlook.com c. Firefox settings autoscrolling, smooth scrolling tried all combinations.

Any fixes?
