About this Add-on
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.

A number of YouTube videos are streamed not only in ADP mode (audio and video in separate streams) but each of those streams in DASH mode (plenty of small segments that need download and rework to create a playable media). Previously, Video DownloadHelper ignored those videos, causing a No media found message to be displayed. With version 6.2.0, you are now offered to download those videos in several quality variants.
HLS-streamed videos have been supported since version 5.5.0 but some servers use encryption on those streams, causing Video DownloadHelper to generate a useless 48 bytes file. This new version supports encrypted HLS.
A number of users complained about not having audio when playing HLS videos using Windows Media Player. This is now fixed and you don't have to use alternative players to hear those videos.
In some cases, HLS captures lead to a file containing only audio. This was due to a bug that has been fixed in this version.
Users with very poor networking conditions like an Internet connection going up and down had a hard time downloading videos, particularly big ones. The new version fixes an issue with chunked downloads not using retries properly, and add a configurable delay between retries.
Version 6.2.0 also fixes an issue with pages containing many videos (like a video-oriented tumblr page). If requesting some downloads and scrolling down to make new videos to be detected, you could lose control of the downloads.
