Firefox miscalculates mp3 audio length
Why does Firefox add approximately 10 seconds to the jwplayer audio bar? Chrome and IE always get it correct. Firefox always gets it wrong. Here's just one example:
http://faithcabot.org/sermons/2016/thechurch/What_Its_All_About.php
The audio duration is 32:13. jwplayer (on Firefox) shows it to be 32:22 instead. Is there anything I'm doing wrong?
