This is the one of best. Because I downloaded 5 popular tools on video downloading from here to download video from a website. The site has so restriction to prevent the video from download. IDM integration, Chrome Extension tools, Developers tools to find downloadable link, all were failed. No one able to capable to download. But this tool also failed to download but its show a tricks in a pop-up window over the video content. "about:config" to change some option. I change accordingly and Allah's!!! I got downloaded the video after 4Hrs of try. Thanks a lot for the whole developer team.
