Stopped working as of Firefox 57.0

I updated my Firefox to 57.0 and this wonderful addon stopped working. 😢

This add-on is not compatible with your version of Firefox.

What happens now?

Viable alternative: https://addons.mozilla.org/en-US/firefox/addon/disable-ctrl-q-and-cmd-q/

The alternative mentioned is not a viable one for Linux users. So I'll reiterate the question: What happens now?

Does not work for me on Linux either.
