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.

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

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

I'm using the latest Firefox. All of a sudden as of this morning, Firefox cannot not load Facebook or Twitter. I can open YouTube and YouTube videos appear but will not play (just a spinning wheel when I try to play). The Amazon landing page is scrambled with code. (see image attached)

I use Ghostery ad blocker but the issue persists when Ghostery is paused. I can use Safari without issue. Can anyone offer any insights?

Latest version of Firefox browser (142.1) recently installed on my laptop and desktop both running Windows 10. The former continues to support Flightradar 24. The latter no longer does. Message reads 'Unfortunately, your current browser does not support WebGL2 . . . most major browsers (including Firefox) do'! Is there a reason for this anomaly, please? Plus a solution?

I have discovered Major problem with Firefox which affects the use of my btinternet.com email account . Since the recent update I am no longer able to add the contact name to a new email which I wish to compose automatically from my contacts (I am required to type it in full. I can still do it, with the shortcut of typing in the first 3 letters, when using other browsers such as Google or Edge or the Outlook muti mail account service but generally prefer Firefox. If this situation prevails I will ditch Firefox as speed of communication and addressing is of the essence to me. Are Firefox aware and are they correcting things?

Could any settings have been altered by the update - which contribute to my problem?

Firefox for Linux can never get past Cloudflare's security captcha. Not just the latest version, but several versions in a row. The page reloads over and over again. Eventually, I launch a different Chromium-based browser and open the page there. Firefox for Android usually handles this issue.

Hi there. The Netflix homepage is no longer displayed properly. Only the headlines are visible without the thumbnails (see screenshot 1). Netflix is properly displayed in screenshot 2 which was taken in an other browser. Can somebody please help me to solve this problem. Many thanks.

Why isn't the Firefox browser supported by many services and social networks? They even state in the warning that Firefox is not supported! Why should users tolerate this?

Почему браузер FireFox не поддерживается многими сервисами и социальными сетями? Так и пишут в предупреждение, что этот браузер FireFox не поддерживается! Почему пользователи должны терпеть это?

Hello,

The fonts are not rendering properly on few websites, example(apnetv.xyz), everything was working fine with stable release of v146.

The beta versions were having the same issue, i assumed it was related to Beta releases, so I switched back to stable one. However now firefox has released stable v147, the issue persists. Kindly fix it.
