Hi, since the latet update thi week (20 november) my F1TV doesnt work anymore via https://f1tv.formula1.com/.

It states : Unsupported Browser

This browser is currently unsupported. To experience F1 TV, please switch to an alternative browser. Please see our FAQs for more information

Pleae help as this weekend is La Vega F1. Thank! Erik.

the browser seems to not render emojis at all anymore instead showing them as blanks browser wide, while other browsers such as chrome and arc and the OS itself are handling it quite well and okay

I'm on windows 11

in the image included, right is chrome on the same website

A few days ago my saved passwords all disappeared. I have been logging in manually and when I do Firefox asks if I want to save the password and I click yes. The password then shows up in the saved Passwords. But... in a day or so it disappears again. What's going on? I have not changed any settings.

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.

Since update yesterday, new tab is empty. Whatever I do, open new tab, open new window, go to `about:newtab` manually, it does not load anything. The view is totally blank. I can navigate to other pages fine as it should though. Only New Tab view is broken. Diagnostic mode does not work. I don't have plugins that would affect New Tab anyways.

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

A heart has recently been included in the Firefox icon in my taskbar. What's the reason for it and what do I have to do so that the Firefox icon no longer has it? I've run a number of antimalware programs and they came up with nothing.

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.
