I'm unable to test Grooveshark right now because it's
unavailable in my country for licensing reasons, and none of the
proxies are fast enough. So I can only suggest the usual suspects:
Disable all add-ons (especially add blockers), or try a fresh
Firefox profile in case something else is interfering.
I found out the problem. It´s because of the media formats that grooveshark
uses (mp3) which the mozilla license does not include. (I´m replying on the
fly and know I´m messing up a bit and my answer is not exactly accurate,
though it was something along those lines)
I offer you a small ray of hope: Mozilla is trying to integrate
GStreamer into Firefox, which should allow us to redirect these
streams through QuickTime. I don't know when this functionality
will be available (probably not in 24, but possibly in a subsequent
version, assuming we can keep the port alive until then).
Dodie, please see the comments above. TenFourFox can't play
Grooveshark music at all right now. If it doesn't work
right in any browser, maybe you're experiencing network problems,
or Grooveshark has technical issues?
