If I open an MP3 file in Microsoft Edge or Google Chrome the soundmanager 360 swf plugin works as expected. If I try to open an MP3 in Firefox 61.x it will not play. The 360 Play animation button does not exist. I do not even get the option to enable it in Firefox. Even if I manually set the permissions to allow flash playback in Firefox it does not play. I can confirm that this issue does not exist in Pydio 8.x using Firefox.
Hi,
if to resume this,
the issue only appears when using Firefox we will take a look at it.
