This downloader is just what I was looking for, it gives you a big green"download" button below the video and when clicked gives resolution options plus the very handy conversion to MP3 at several bit rates.
I did have problems to get it to convert to MP3 even after upgrading to Pro, but after sending an email to the developer, Deepesh, I recieved the solution with the hour, i just had to disable all addons in Firefox.
I then enabled them one by one to find the blocker.
Well worth the 10 bucks for the Pro to enable MP3 creation. (and 1080 HD download) all with just 2 clicks.
