Works great on Manjaro, after the required `plasma-browser-integration` package is installed. I really love it!

Its not running on firefox 64 and Manjaro 18.0 - Kernel Linux 4.19.12 - Plasma 5.14.

A must have for KDE Plasma users and further proof that KDE is a cut above the competition.

Awesome - I can now pause google music (and anything else) running in firefox with my media keys

Very successful and doing this job well.

Very good idea and well executed. Works really good! Quality of KDE Community as always! This is one of the things that I like most about KDE Plasma desktop experience.
