Firefox broken after installation of this addon

Works flawlessly!

Extension indispensable pour Plasma by KDE qui fait son job sous GNU/Linux. Merci pour le boulot.

A necessity for any KDE user.

Soundcloud cover doesn't show up, will rate 5 stars after next patch update regarding this.

Very useful when working in the KDE plasma desktop environment. Gives you a lot of options and ways to control firefox right from the desktop. Makes firefox feel like a system app. Quite easy and fluid to use with KDE. I recommend this extension to all KDE user.

The initial state was interesting and it keeps improving!
