simple addon and very usefull

perfect

I have been using this app for a while and have consistently been happy with the app. I have had little to no problems with Video DownloadHelper and it saved me several times when I needed to get a certain video downloaded. This app is easy, efficient, and reliable.

Perfect!

The only downloader you will ever need!

very good add !
