here some (german) examples:
http://www.klassikradio.de/webplayer
=> says that my browser is not supported anymore, and I should use a modern browser
http://www.radio.de -or- http://www.radio.com
=> nothing happens when I choose a radio station (loading and loading forever)
http://www.duden.de/rechtschreibung/Kaenguru
=> scroll to the middle of the page and click on the little "speaker" button (.mp3) for spelling => nothing happens
But it fully works with _Firefox_ on Linux, so all needed packages are installed! (gstreamer and others)
And the pages/streams work when Palemoon is running on _Windows_!
I've tested it with the previous version of Palemoon (25.x) and the latest (26.0), with the same results.
Windows 7:
-----------
Firefox: working!
Palemoon: working!
IE11: working!
Linux (Manjaro):
----------------
Firefox: working!
Palemoon: NOT WORKING!
Midori: working!
