Video DownloadHelper is the most complete tool to extract videos and image files from Web sites and save them to your hard drive.
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.
