Some video downloader plugins don't work on some sites. I use "CocoCut Pro" when there isn't a download option on a website. It works really well. As for Eporner, when you click download from this site, you need to scroll down and it will show you all the options for downloading the file. Anywhere from 240P all the way up to the highest resolution. I tested all my videos and they are all working just fine. I use AVG Secure Browser because it has better protection against sites with malware and viruses. I highly recommend AVG Secure Browser. It's better than Chrome.
