I installed Freemake this morning...I'm still cussing you. it downloaded some file to check my computer and all I have to do is pay for a registration, and it can fix all the errors. What a deal! I haven't had that happen since my AOL days, and I left them in the mid-90's.
Firefox does have an add-on that allows you to search youtube for specific songs and/or artists. It has a download feature that allows you to save as an MP3 format file. I still need the freemake, though, for longer than 20 minute songs like the one I posted earlier.
