I'm not using the same version, but it worked after it loaded (too much CPU on 75.0), but instead an html5 player (I don't know if it is that what should happen), it launched a download/open dialog fore the .m3u file link, which launched Winamp to play its stream
http://east-mp3-128.streamthejazzgroove.com/stream
If you use or want to use a player (Windows Media Player, Winamp, VLC, whatever), maybe you could think about to play that streaming through it with that URL.
Better than the above stream URL:
https://jazzgroove.org/jazzgroove-mix-1.m3u
EDIT: just tested with Seamonkey and behaves the same and the Listen link works.
Might be that you don't have a default action for m3u files?
Go to about:preferences and applications section (make a profile backup first) and have a look to it and change options accordingly.
