Unity Web Player Firefox

Iam trying to get a web-game working,that needs Unity,but I noticed that Firefox doesn’t support it anymore. Is there a way I could downgrade Firefox so that I can use Unity again? The add-on that is supposed to replace Unity doesn’t do it’s job right, so that’s why I’am writing this e-mail. Apr 28, 2020 Unity Web Player is a browser-based version of the graphics engine designed by the same company called Unity. It includes advanced rendering technology that allows you to load games and 3D applications in your web browser like Chrome, Firefox or IE. Unity Web Player installs in very little time and works in most browsers.

Hello everyone!
It appears to me Itchio has made all Unity Web Player games (Not WebGL) refuse to load in, even when using an appropriate browser to do so. At first I thought Web Player had been completely removed even past Chrome doing so years ago, but just recently connected the dots that the only games that don't load are on here. Gamejolt, blogs, Ludum Dare, etc. - all load just fine.
It may seem silly, but I would very much like to download some of these little gems. I have been passionate about freeware gaming since 2007, and have around ten thousand freeware PC games on my backup drive today. I have been developing games myself the last five years or so and a lot of the games made by developers on here, or I discovered through here are extremely nostalgic for me and important in the way any good video game is to a gamer.

It never fails to surprise me how many gamer's not only are unaware of how big the indie scene is, but how vast the freeware gaming scene is these days too. The massive collection of freeware games I have has been essential to starting friendships and opening up a common ground with people I otherwise wouldn't get to do.
So, what I'm getting at is I would very much like to get a few of these games while still possible. I just found out Firefox and several other browsers are making NPAPI completely unusable like Chrome in early 2018. With tech like the web player so old as it is, there will only be so much more time left to use old builds of web browsers just to utilize even older plugins.
I can understand if Itch is trying to completely move away from the web player format all together. At the same time I want to voice some way of obtaining the .unity3d file for offline play in the future.
It's impossible to download the file if it isn't loaded in the plugin, so that's why this is an issue. There are dozens of silly prototypes and couch co-op games that I have fond memories of as well as talk about to my fellow devs and gamer friends almost every day. I know I'm a broken record saying I would very much like to hear how to go about this, but hopefully it is clear this is important to me, and I can imagine most people here understand why, even if it is a bit excessive! XD
I apologize for the rant, as well as this being my first post. I have been holding off being active on any site for indie gaming as I have several things that have been in the works for years I plan on releasing in 2018 right outta nowhere like an RKO. however I'm afraid this post is actually more important to me at the moment, especially since it's time sensitive.

Thank to anyone who even bothered to read all this, looking forward to getting to know more fellow devs and indie gamers.

P.S. Yes, I know this issue was raised on the GitHub issue tracker. However, nobody has responded to ompuco's issue from October, so I wanted to post here as another six months and these games may be completly gone forever.
