Who knew that Firefox had so many add-ons? Want to download a Flash movie from a website like YouTube or even NBC News? There are 21 ways to do it within Firefox.

After this, it’s a piece of cake. Go to the website containing the video you wish to download. When the video that you want to download begins to play, pull down the arrow menu and select “Try Alternative Download.”
