Just surf the Web as you are used to, when DownloadHelper detects it can do something for you, the toolbar icon highlights and a menu allows you to download files by simply clicking an item.
For instance, if you go to a YouTube page, you'll be able to download the video directly on your file system. It also works with most video sites like DailyMotion, Facebook, Periscope, Vimeo, Twitch, Liveleak, Vine, UStream, Fox, Bloomberg, RAI, France 2-3, Break, Metacafe and thousands others.
Video DownloadHelper supports several types of streamings, making the add-on unique amongst Video downloaders: HTTP, MP2T, F4F, … Whenever a site uses a non-supported streaming technology, Video DownloadHelper is also able to capture directly from the screen and generate a video file out of it.
As a bonus, Video DownloadHelper can also record Twitter Periscope. Just specify search terms and the add-on will capture over night related live streams.
As another bonus, you can also use Video DownloadHelper to capture a full browsing session, optionally highlighting the mouse position and generate a video file out of it. This is ideal to create Web a site demos as a video.
Besides downloading, Video DownloadHelper is also able to make video conversion (changing audio and video formats) and aggregation (joining separate audio and video to a single file) very easy. This is a commercial feature that helps paying for the free stuff (we need to eat too). You are not compelled to use conversion for downloading videos from web sites, and you can avoid picking variants marked as ADP to avoid the need for aggregation.
When you first install the extension, your browser is redirected to a welcome page with links to a user manual at http://www.downloadhelper.net/howto.php.
This does not change your homepage setting and the welcome page won't appear anymore.

You may have noticed that for some time, downloaded videos from Vimeo (or from sites hosting their videos on Vimeo) do not have audio.
This is due a change in their streaming technology and they now stream the audio and video parts of the media separately, as YouTube have been doing for several years.
The Video DownloadHelper workaround is the same as with YouTube: use an external video converter to aggregate audio and video streams into a single audio+video file that can be used by your video player.
We are aware of the inconvenience of having to install an external application, but there is no easy alternative here. Note that once the converter is installed, the process is totally transparent and you end up with a fully playable video without any special action.
If you want to avoid using the converter, you can still use Video DownloadHelper to download separately the two streams (but you will have to find a way to play them together). For doing so, open DownloadHelper settings > More > Chunked streaming, check Advanced. In section DASH streaming, parameter When DASH contains both audio and video lets you choose which stream(s) you want to download. Default is Aggregate audio and video, which implies using the converter but you can change it to choose audio or video only.
