Save link as option vanished in firefox 17.0.So now not able to download mp3 files.Instead click on mp3 files starts playing in some black player in firefox. Earlier i was able to download mp3 files by pressing on link for some time and menu popus up "Save link as" but after recent update that option is gone. That option is desperately needed. One more thing is MP3 file start playing in black player on firefox when i actually want to download them and then play it. fix this issue ASAP.
