can no longer play Unity games on Mozilla
Games that run on Unity are no longer working on Mozilla Firefox, it has been a problem for me for the past few months. Whenever I open a website with Unity games the message "Update Unity to latest version" pops up. I tried downloading the latest Unity, but the problem keeps coming back. I have downloaded it many times.

I believe you need a web browser that still supports NPAPI plugins. Firefox no longer supports those. Have you been to the games forum pages. That might be the place to go to find out what is going on with the games, what others are doing/using. https://forum.unity3d.com/
Please let us know if this solved your issue or if need further assistance.
