Been using this for many years, now. An excellent extension. Does exactly what it claims. Most other extensions of this type that I have tried, appear to get confused by some media formats. That hasn't happened with DownloadHelper as yet. Highly recommend.

This app/add on is fantastic. I am an engineering student who has ALOT of online lectures to go through. I HAVE to download all of them, every class builds on the next. The videos come from alot of media, this extension is the only one that has successfully downloaded all the media from the various sources. It is much better than sketchier tools that i have used. The only time it CANT work is when the media uploads through a third party popup, ie blackboard collaborate. But no app I know of can.

me gusta, ya que la descarga es eficiente y de calidad, gracias

非常好用

if you are looking for a simple and no nonsense downloader, this is it.

still cannot download? the likelihood the website the user entered has download restrictions are extremely high, from my experience.

all in all, love the apps. 5 stars for the continuing good work.

Great add-on for downloading videos from many sites, very easy to use.

Really good and straightforward user interface. Highly recommend this extension. I would really like to thank the developers for such a great extension.

Excellent video downloading application. Very transparent app

This is wonderful app since it has launched. I really thank to the team and their good efforts.

Ich bin sehr glücklich mit dem DownloadHelper. Habe schon viele Filme damit heruntergeladen und möchte dieses AddOn auf keinen Fall missen.

This add on helps me everywhere

video downloader has worked really well for me. But recently you tube videos are not offering formats that I can use anymore.

Have used it for years. It works quite well, in spite of websites frequently changing code to disallow video downloads. I highly recommend this mature, working, safe, reliable add-on. This alone makes firefox my browser of choice!
Update: I've now used it for another year and the active development is a great feature - when a site blocks downloads within a short time Video DownloadHelper is modified and works again. This is great software.
