Used to be great, but after the latest update, the addon shows a blank page even though the media is detected.

Not good, not bad. It worked for me so I'm happy. But if it's about implementation of this extension then its really bad. First of there aren't any data about the download. You don't know the speed, how big the video is, how long will it take to download etc. Also every download is a separate window. It should work like a floating window that works in background. Something like in other extensions (for example Video DownloadHelper). So I'm looking forward to download an updated version of your extension. At the end Thank You!!!
