Windows 10: Remove duplicate Firefox installation cleanly

Version 1909

Somehow I ended up with two Firefoxes installed. (It pretty much has to be my fault).
They are both 64 bit and the same version. One is in Program Files/Mozilla Firefox and the other is in Users/xxxx/AppData/Local/Mozilla Firefox.
If I go into Settings/Apps & Features it only shows one Firefox and if I go to uninstall from there it does not show any clues as to which one would be uninstalled or maybe both, who knows - it is not very informative or friendly there.
I would like to keep the one in Program Files. Is there a way to uninstall the one in Users in a clean way that will clean up the registry too? (There are over 100 instances of that path in the registry) Could it be as simple as running the uninstall helper.exe in that folder?
Or should I uninstall both and reinstall one? And will that clean up the registry? This is a fairly new Windows install, I hate to see it all polluted already.

This should be easy but I am new to Windows 10 so of course it isn't.

Removing duplicate app entries from the default files list

I removed a program (Firefox) from my system, but when I go to Default Apps and click on the default (now Chrome) browser, Firefox remains in the options list even though I just uninstalled it. I uninstalled Firefox because I was getting multiple entries
for it in the Default Apps list, and intended to remove the remaining duplicate entry. How do I do that?

 

Removing duplicate app entries from the default files list

Hi Roger,

There's a possibility that Firefox isn't uninstalled completely on your computer. We suggest that you uninstall it in the
Settings app by following these steps:

• On Start, select that cog icon or Settings.
• Go to Apps and select the program that you want to uninstall.
• Select Uninstall and follow the instructions on the screen.

This will completely remove Firefox from your system and from the Default Apps list. You can also check and save this article that in case you need a guide to

repair or remove programs in Windows 10.

How to remove duplicate files in Windows 10.

Thank you for the suggestion. I need to see a list of duplicate files and select those I want to eliminate. Does the program you suggested compare file content or do they simply point out duplicate
file names?
