User.js: Music on VK

[bonbonboi]

I've an issue in playing audio music on VK.com getting this message:

Error
An error occurred while downloading the audio file. Please try refreshing the page

of course I did refresh, still the same, I'm troubleshooting this issue, any tips would be appreciated.

PS> that issue never appear with FF defaults.

ok, solved by

/* 2030: disable auto-play of HTML5 media

• [WARNING] This may break video playback on various sites /
  user_pref("media.autoplay.enabled", *true);

and disable tracking protection.

Thanks,
