Firefox: YouTube is a video site, but it’s got one of the best music selections on the net. Use that to your advantage with FoxyTunes’ latest update, which can play YouTube videos and playlists like any other music source.
The downside for those trying to save memory or browser tabs is that YouTube still has to be open in at least one tab while using FoxyTunes’ controls, but that’s not to say you can’t just load up a YouTube playlist, ignore the tab, and then play, pause, skip and rewind at your leisure. All the other FoxyTunes benefits—song info, artist links, scrolling playlist information—are present for YouTube clips, and it worked pretty much flawlessly in a few tests.
FoxyTunes is a free download, works wherever Firefox does. Existing FoxyTunes users may need to head to the FoxyTunes site to grab a version newer than the one offered on Mozilla’s Add-Ons site.
