It need some work. Does functions with Youtube but only when Firefox is in active-focus state. Doesn't work with Anesidora (Pandora player).

All the buttons I'm using control only play/pause, despite the add-on recognizing the different keystrokes

Works properly

doesn't work on spotify

Version 2.5.2 - all media keys work as play\pause on google play music. Also it's a bit annoying, if I have VK and Google Play Music opened at the same time (both tabs are opened), VK receives the commands.

(2020-09-25) Just used it on soundcloud. It works :)

Very useful addon. Along with this simple ahk script it works in non-focused browser window

Media_Play_Pause::ControlSend,, {Media_Play_Pause},

They mentioned a Firefox bug causing only Play/Pause buttons to work, but they only work when the browser's in focus. Useless when you want to pause a song or video while in another window or a game.

doesn't work

какая-то херня, которая совершенно никак не работает. ни на пандоре, ни на ютубе, ни на спотифае.

Nem működik. Sokkal jobb a Play/Pause, szerző: Daniel Kamkha - ott van egy gyorsbillentyű is, itt hiába állítom be. Ezenkívül rengeteg engedélyt kér, ami persze a használt oldalak miatt is lehet de az említett plugin ezt is megoldja!

all my media buttons(stop, skip back, pause/play, & skip forwards) pause/play the supported apps listed in the description of witch I only use one consistently and only works at all if firefox is the focused app so if I am playing games or do anything that is not in the browser the music is playing in it does not work at!!! DO NOT DOWNLOAD!!!!

Play/pause only

not working with youtube
