I do have the latest version & it still Does Not Work. Too bad...This review is for a previous version of the add-on (184.108.40.206-signed).
"Doesn't work" is just something generic. What doesn't work? You can't download a certain video? You get a blank window after downloading a video? I tested the extension a few minutes ago and it works well even for VEVO videos, but YouTube tests all kinds of features that are only available to x% of the users.
