HTC One X+., Android v4.1.1, Firefox 19 and Firefox Beta 20 for Android Attempting to select an mp3 audio file for playback causes Firefox 19 to give the error message "Video can't be played because the file is corrupt." Replicating the issue causes Firefox Beta 20 to crash without any error message. There is also no option to "save link as" to see if playback from the downloads folder will also cause an error, although it appears that option will be added to Firefox 21. The site I am attempting to download from is http://prestonandsteve.libsyn.com/ although other sites with audio files have given me the same error. This problem does not occur in the stock Android browser, Chrome, Dolphin, or Opera browsers and they are all able to either playback or download the audio files.
