Mozilla Firefox addon which collects URLs of viewed videos
While you're viewing a flash video Video Sniffer trying to sniff the link to the video and collect it to the "Collected Videos" context menu so you can download it later. New links will be added at the top of the list. Only limited number of links are collected (currently 20) and old links are removed to free the space. To clear all collected links manually just click on "Clear List" menu item.
