Cannot run play.spotify.com

Spotify complains about not supporting QBRT. I haven't looked into why this is the case, but maybe a lack of DRM + some user-agent/js detection?

The issue is light for now as I don't have a lot of details, but I might look at it more if I have more time.

Can confirm that they're using UA detection as setting application.ini to that of a regular Firefox browser will allow me to login. However, DRM doesn't seem to exist with QBRT and thus cannot playback Spotify yet.

In theory, qbrt should support the same web platform features as Firefox. Do you know the particular "DRM" feature that qbrt would need to support in order for Spotify to play music?

I believe this is downloadable module which needs to be enabled. I'm not sure how this would be downloaded in qbrt, tho.

Hmm, qbrt would need to at least set a couple of runtime preferences. qbrt doesn't currently support an app setting runtime preferences (#73), but you could manually edit qbrt's defaults/preferences/prefs.js file to set those preferences.

However, I'm unsure if that's sufficient to enable/download the WideVine CDM that Spotify presumably needs to play music. It might be necessary to do something else, such as loading browser/base/content/browser-media.js into the shell. More research is needed.
