Win XP, Firefox 33.11. In an html document are links to PCM, 16 bit .wav files and other links to .mp3 files. Opening the document with Firefox and clicking on an .mp3 link plays in the `native' Firefox player OK. However clicking on a .wav link seemed to fail to play. Using Tool/Options/Applications, wav files were associated with VLC. Now clicking on a .wav link plays OK in a Firefox screen displaying the vlc logo. However, later the following was found this under the Firefox help information "Firefox can play the WAV container format (.wav, .wave file types) containing uncompressed audio in PCM at 8 or 16 bits per sample". It seems the .wav files should play with the `native' Firefox player. How can the link to vlc be removed. Removing the plug-in is not a solution as it is used for many other file types.
