Download Helper is a nifty addon to download any video/audio/image that you may be viewing on a website. After installing the addon you get a small three balled icon in your toolbar.

The icon becomes animated if there is some content available for download on a website. You can click on ‘down arrow’ right of the icon and select the video/audio you want to download.

In case multiple-streams of same video (usually of different quality) are available it will show you an option to download any one of them. This feature is especially useful for quickly browsing through your videos in Low Quality mode but downloading the high quality video for later viewing.

Clicking on the chosen video will download that video to the default location.

Further the addon also make some commonly used tasks after video download easier. It gives user the option to get the raw URL of video which can be plugged into other softwares, to tweet the video to their twitter account, to convert the video after downloading & to secure the videos with the password on local drive. The last two options require two separate addons from the same developer.

As a last feature, the Downloader Helper also features a list of sites ,along with their ratings, from where free videos are availalble. You can get this list by clicking on the icon itself.
