Resetting how files open
So I don't know the proper way to word this, I guess I'll just ramble until my point gets across. A couple years ago I downloaded Optifine, because I just wanted to experience Minecraft in ultra hyper 4k whatever. I didn't quite understand how to open it to install it or move it into a file or however that's done. I still don't quite understand. In my confusion, I decided it would be a good idea to change the default way the file opened to into Firefox. Now when I double-click to open it, it opens a new firefox window and asks where I want to save the file. My question: how can I change the file back to what it used to be? Apparently it's supposed to be a .jar, but I'm not seeing it anywhere on the file. Alternatively, if reversing the file type isn't an option, does anyone know how I might be able to install it? Please I'm begging T-T
This is what the most current file name is: OptiFine_1.20.1_HD_U_I5
Sidenote I just checked apparently it IS STILL a .jar file, but I don't have a clue what to do with it aaaaaaaaaaaaa

You can check specific file extension keys in the registry with the registry editor.
- HKEY_CLASSES_ROOT\.xxx
You can check possibly linked MIME types in the MIME Database registry key.
- HKEY_CLASSES_ROOT\MIME\Database\Content Type\
In Firefox, this is stored in handlers.json in the Firefox profile folder.
You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
