Cannot add an engine: "Firefox could not install the search engine from: https://file.io/8FYC27VcLq9Q"

Hi,
Firstly, thank you for creating this addon, it's a great thing!

I get this error,
Firefox could not install the search engine from: https://file.io/8FYC27VcLq9Q
while trying to add:
Name: IMG
SearchURL: https://www.google.com/images?q=%s

It would be awesome to be able to setup this engine.

You are using an outdated version. I stopped using file.io since Jun 23, 2020 in Version 3.0.
