When batch downloading k2s.cc video links from a website. Some will download fine. But plenty others won't have the name of the file. But instead the name of the link, an html extensions and the proper video size. Others will also download the link.html but only a 4kb file. If I download those links manually : they work fine.
Nice extension, no doubt. But I spend more time figuring out what's missing, what names should be, etc.
