Hi.
Been awhile since i have visited song forum.
Has something changed here because all the “song links” that other people have done are invisible ?
Do i need to change something my renoise profile settings to see these soundcould links ?
Or is it that firefox dont show these media links anymore ?
Cheeeers 
Mm, works fine here? Win8.1, Firefox v50.1 (15.december 2016)
Actually, I prefer using Firefox for listening as the embedded SC player for some reason has been broken for the longest time on Chrome - not just on our forum, but anywhere, it seems. And by “broken” I mean that you can’t click the waveform (using the mouse) to take you to a specific time. Only seems possible when using arrow keys, or by going to the soundcloud site and use the player in the bottom of the screen.
Same problem here as OP, and opposite to Danoise:
No SoundCloud player in Firefox (v50.1), Win 10, just empty boxes. I have to use Chrome for forum listening. In Chrome all working fine.
I thought it was some flash update problem but no help. ( Is there anything flash in web nowadays even ? )
I really have not yet solved this, I have so little understanding about these browsers so I have no clue where to start debuggin.
I would prefer using Firefox though.
Anyone have deeper knowledge on this ? Or any tips on how to track what causes this ?
adblocker / ghostery / noscript issues?
Flash is getting deactivated by default on more and more browser.
Can you right-click on the object and activate the plugin?
