Fix needed since the last Google Music update. Rated 5 out of 5 stars

Google changed the web interface in 05/2015, so the addon doesn't work anymore. I'm using this temporary fix until the author fixes the addon officially: edit the file %APPDATA%\Mozilla\Firefox\Profiles\[your_profile]\extensions\{cad52e60-d607-11e2-8b8b-0800200c9a66}\content\browserOverlay.js, on line 219 replace getElementsByTagName("button") by getElementsByTagName("sj-icon-button")

No longer works since May 14, 2015 Rated 3 out of 5 stars

Worked perfectly before May 14, 2015 update. Useless now because it no longer works. If anyone knows a fix, that would be awesome.

It doesn't seem to work very well with Firefox 64-bit but I don't really know how to debug that situation, maybe a problem with loading a 32-bit dll in a 64-bit process ?

Doesn't work. I've tried everything I can think of. A similar app, Prime Music, for Chrome works flawlessly and gives you much better interaction, notifications, etc.

Works like a charm Rated 4 out of 5 stars

Only downside is that I have to close the Logitech SetPoint software to make it work.

Two caveats:
- needs restarting
- stop key doesn't work

Otherwise great ;)

Great extention, works well Rated 5 out of 5 stars

Ok, this is awesome. I'm currently using the Corsair K70 keyboard, which has media keys, and so far all of them seem to work fine.

Awesome Rated 5 out of 5 stars

I was struggling with moving to Google Play from iTunes Match as it didn't have a desktop app that I could use with my keyboard's media keys. I decided to check for an addon and lo and behold I find this one. And it just works, no problems, no gotchas. Kudos!

This is the best addon ! I'm using it all the time while browsing, playing games like BF4 etc... I'm using a Logitech G710+. One thing that would be nice is to have the option to define custom shortcut for example to 'thumb up' or 'thumb down' songs while they play. Anyway thanks a lot for this

Very, very good, bar one minor thing Rated 4 out of 5 stars

This excellent extension does exactly what it should, and I can now use my keyboard's media keys to control playback with Google Music.

There's just one downside - it doesn't work with the Nightly build of Firefox (which I use for the 64-bit compatibility). I imagine this is a problem with the new UI, Australis. Hopefully the developer can fix this soon.
