Can we get a version that's compatible with FF 61.0.1 ???

Esta valoración es de una versión anterior del complemento (1.9). 

Sorry but Mozilla closed the door to this type of modification. You can't do this with Web extensions. You're best bet is switching to Waterfox like I did.

The extension was working until Firefox 57 then they decided to blow up legacy extensions and close many possibilities for us Addons developers.
