Rated 4 out of 5 stars
I use it every day and it is of great help!
I can really download videos from youtube and youtube-like websites. I can also download almost almost all the music embed on sites.
I'm very fund of this add-on and I highly recommend it.
But, I give him only 4 stars because I observed it can't download videos from certain websites. For example, from rajshri.com. I don't know what type of video is there, but I observed that some video formats just can't be captured and downloaded with this add-on. And I don't know which add-on could help me. This thing is one very unpleasant surprise.
Anyway, till this problem is solved, I give it only 4 stars. If that feature will be added, then the add-on will be absolutely perfect!
Congrats for the developer for the good job, and keep it that way!
