Rated 5 out of 5 stars
I'd been using "Flash Video Downloader" to DL YouTube vids for a year or so, but it stopped working, even after making sure it was current. I tried many times, all their various extensions, but each DL was *empty*.
Uninstalled, then installed this addon, is actually DL'ing a YouTube vid - properly! - as I'm writing this review. And it's not as complicated as "Flash Video Downloader" either. Thank you!
