If you love music but hate jumping from Firefox to music player and back whenever you want to adjust your tunes, FoxyTunes is the plug-in for you.
FoxyTunes gives you control of your favorite music player from within Firefox, so there's no more switching windows to skip that Barry Manilow ditty you forgot to delete. The interface is easy to use and is highly customizable. When opened, it shows a navigation array with buttons for Play, Pause, Mute, Next Track, Last Track, Volume, and the useful Show Player, which unhides your music player. There's also a Hide Player button, as well as a music Search tool, keyboard shortcuts, skins, and a mini player that places the app controls on your desktop.
Supported players include iTunes, Winamp, RealPlayer, XMPlay and Last.fm, as well as nearly two dozen others and a "custom player" option. The lyric and album art searches have been expanded with FoxyTunes' new music portal, which provides feeds from Google, YouTube, Amazon.com, Last.fm, Wikipedia, and several online radio stations to make music discovery easier.
FoxyTunes' strengths are in the depth of available features plus the level of customization. Weaknesses? Only that you'll wish all Firefox add-ons were this good.
