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 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.

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

So Im currently trying to watch young sheldon on netflix, and im doing it through firefox, and it wont work, it says error code f7701-1003, thank you for your time.

Some recent update has changed the way extensions function in Firefox. I used to be able to pin my extensions on the toolbar between the account icon and the extension icon on the toolbar. This is REQUIRED for certain extensions to function properly. One example is uBlock; when visiting a site it actively updates the icon letting you know its working and blocking unwanted items. Same with Facebook Container. Password managers such as 1Password also have stopped working for me unless they are pinned to the toolbar. You use to be able to click the extension icon and then see the list of extensions in a window. Now when you click the extension icon it opens to the Recommendations tab of Add-on Manager. You then navigate to extensions and see you enabled extensions but there is no option to pin, only manage/remove/report. I was able to fix this behavior once by completely uninstalling Firefox and then removing the left over folders on the C: drive. Once I reinstalled and went through the initial process of adding the extension, it also asked me if I wanted to pin to the toolbar. To which I said yes and got things working again. After clearing my browser history and cookies, then turning that feature off, it also blew away my pinned extensions. Even after removing the extension and re-adding, I do not get the prompt to pin like I mentioned above. So its seems I may have to go back and uninstall/delete folders/reinstall to get this working again. I see several similar posts so this appears to be either a bug or a very poor design choice on the part of Mozilla.

How do I fix this? I'm not able to use any of my extensions now and really don't want to have to randomly uninstall/reinstall every time this issue happens.

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.

I can't re-open a saved tab group. I saved it and closed firefox but when I returned I couldn't find where to access it. I see all of my saved tabs when I right-click on a tab and choose "Add Tab to Group", but when I move the tab to that group it just disappears rather than open the group. Any help would be appreciated! :)

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?

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.
