Copy function is broken in FF15. Rated 5 out of 5 stars

First of all, this is a quintessential addon for me. I have been using it since the days of FF2 and i can't do without it. It is one of the little addons with a simple concept which completely transforms and enhances the experience of surfing.
Unfortunately in FF15 the copy button of the addon has stopped working. The save and info buttons do work but i don't if it is the same case for the print and folder buttons since i never use them.

If the developer is reading this, could he please fix this problem? Otherwise i ll have to revert back to FF14 in order to keep using this sweet addon. ;/

This review is for a previous version of the add-on (0.6.9).
