I like two legacy add-ons "Show Parent Folder" and "Go Parent Folder" that are no longer available for download, as the developer no longer has a "previous versions" web page -- or any English language page.

I have three Windows 10 computers networked together, one running Firefox 56.0.2 and having those add-ons installed in it. I want the other two computers to get the add-ons. They run Firefox 52.5.2 ESR.

Since I cannot install the add-ons from the internet, how can I get them one computer to the other two?

Hi StanH !

Would you take a look at the Chosen Solution in this thread, and see if that will work for you too ?

Simply copy them from one computer to the other & install them locally.
On the computer where you have them installed, they're in the /extensions/ directory in your Profile folder.
If they are not "identifiable" in the /extensions/ directory, about:support will have a mapping of the GUID -> common name.
