This is an answer to a previous question of yours which i failed to find!
You were looking for a video link.This is called Free Download Helper,
which is very versatile and works with lots of sites,and has quite a few features
aswell. When you download it ,a tri-coloured icon will appear next to the address bar
on the left.Just click on any supported video and it will rotate,then click on it to show
what you're watching,and click on download at the top,that's it.hope you like it!!
