I don't have an answer, but I am interested. That said, apparently Firefox can now import and use Chrome extensions with the new update. I have yet to try it myself and assume your mileage will vary.

The import requires the extension to also be available on Firefox
Have you tried running the extension on Firefox?

This is just importing a list of extensions from chrome and matching them to a Firefox extension. If the extension doesn't have a Firefox version it won't fo anything.
