Despite the suggestion, i'm going with Great, but not perfect. Why? Incredibly easy to use, quite reliable over any type of connection, and accurate reproduction. Only drawbacks are inherent in youtube and videos in general (filesize, and time to download at higher resolutions).

I have tried over a dozen video download programs and this one has consistently been the best. Various changes take place in video handling on the Internet which often 'break' these down-loaders. It seems that Video DownloadHelper is the first to 'recover' from such changes.

The interface is pretty good though it is UI issues that stop me from providing a 5-star rating. As with any 'drop-down' space is limited. However, the lack of ability to find more detail about choices presented means that often it is just a 'crap shoot' about which option will both work and provide the type of download that you want.

Not that content producers or content suppliers will read reviews but on the oft chance that they might...
Some of us live is rural or semi-rural areas where Internet service is neither really fast or consistent. Attempting to watch many videos on-line is really difficult because of frequent delays. Thus, downloading and watching a local copy with a video player is the only practical way to view many videos.

Uso da alcuni mesi Video DownloadHelper e lo trovo facile e intuitivo da utilizzare, anche se mi piacerebbe fosse più veloce, se possibile, nei tempi di scaricamento.

Video DownloadHelper is extremely easy to use and works well with FireFox Browser. A handy little tool which has stood the test of time and has remained user friendly and efficient.

Este complemento para Mozilla Firefox es muy bueno para bajar los videos de Flash Player, lo recomiendo por su uso sencillo.

很方便的下載元件

I don't as a rule agree to downloads or add-ons of any kind. Same applies to Mozilla downloads. I took a shot at this one and i'm pleasantly surprised. I works surprisingly well and easily. It required some seek and find to discover where the downloads are filed. In my case it turned out to be the system's downloads file. The drop-down menu provides an array of file download format choices that should satisfy most PC users.
