Trouble-free, simple, almost invisible; there's a companion app for use on some troublesome websites (e.g. YouTube), but the extension works on most by itself and does everything I expect and nothing I don't. The companion app is trouble-free too, once it's installed. If you want quick 'n' dirty, this is a quick one that's pretty darn clean to boot.

A Must have add on, downloads all sorts of Online Videos

Semplice e facile da utilizzare. Lo installi, clicchi sull'icona e scarichi il video che stai guardando. Consigliatissimo!

Congratulations !

Absolute rubbish! This useless extension requires Firefox, a "companion app" and an 18.50 EUR licence to convert videos to audio and to remove its QR watermark from downloaded videos. Do NOT bother downloading it if you value your time.

[Video DownloadHelper] It’s a great download software. You can use it with confidence. I have used it many times.

This is the best add-on for mozilla firefox to download anything you want, download this add-on as well as donate for support as well as become premium membership for more advantages for using this add-on.

I have been using this add-on for over 5 years, and it's still going and I love it, you should try it now, moreover you should add-it, use it then you'll know that this is the best for any website you use it on.
