I used this addon for a long time, and it generally worked. Recently I decided to download some videos my personal friend made that were funny. First thing I've noticed is this addon was very buggy on Firefox. I don't know if it's just my computer, my particular Firefox browser, or what. I tried to download and upon trying to click the link it fails to actually download. It's very buggy and I have not been able to get it to work. If this is indeed maintained by one developer then I must say he needs to really improve the reliability of this addon. Very disappointed in this, especially since I know this addon worked better in the past.
