Works just fine even when using from LibreWolf.

Many people say this addon does nothing but for me it's perfectly working. Maybe the problem has been fixed? I'm on Mac if that matters.

This addon is not working. How is it even supposed to work? Using latest firefox realease to current date. Freetube is installed on my machine.

EDIT:
It is fully working now. Do not know where might be the problem, but clicking link in browser shows option to open in FreeTube app. Good work.

simply does what it is supposed to do.
