As most of you know, if you open a Youtube video, and then look at HTML source in browser, then you can get download link (if you know where to find) Now the thing is, if I open a video in IE, copy download video link from HTML source and then paste it in another IE window to download then it doesn't work. But if do the same in Chrome i.e. first open video, then copy download link from HTML source and then paste it in another Chrome window to download then it works! Even using Firefox, that download video link doesn't work. And this is because there is a slight difference in download links between Chrome, IE and Firefox. Isn't it strange!? Why would Youtube do that? Why this works in Chrome only? Anyone else noticed this?
