This is a really very good software. It also can cover and support most of the video types for downloading.

I've used this add-on for about 10 years. As YouTube evolves, some of their videos can no longer be downloaded with this add-on, but it's still good to have, and they do update it from time to time. If Download Helper can't download the video I want, I use another add-on or method, such as Easy Youtube Video Downloader Express, or I use VLC media player, or any other number of methods. DownloadHelper is a good and old tool in my digital toolbox, although it certainly can not do everything, and sometimes depending on how the video is downloaded, there is a watermark.

Works flawlessly, but the interface is not displayed entirely when the add-on is in the overflow menu.

Very nice add-on

Instructions are a bit confusing, almost inscrutable, but perseverance pays. Once understood, it works marvelously

Today I have reached my 100. Download...So it works.
Unfortunatly I cant get a lizense cause I have no Credit-Card.

works well but I have 2 computers that have crashed and need to remove them off of my list that are active

Non è velocissimo ma un buon strumento per lo scarico dei file video
