Despite mighty_maite's suggestion clearing the youtube cookies did not help, even after restarting FF. Win7 64 bit, FF 14.0.1, Download Helper 4.9.9. No other methods worked (e.g. tried MP4 Downloader 1.3.2 or the Keep Tube service) until I remembered a free program called jdownloader (http://jdownloader.org/). I installed it (btw only the offline installer, at the bottom of the download page worked). It needs recent java6, the version 2, which is still in beta is supposed to be java7 compatible, but I didn't give it a try. After that, finally I could download the video from youtube with jdownloader. So much about the downloader add-ons, unfortunately. :(

This review is for a previous version of the add-on (4.9.9.1-signed).
