Everytime I try & run this addon to DL a video in FF v. 57, I get the following msg.: "Native application is not installed. In order to download streaming videos you need to install native application.
Would you like to install it now?" I then DL said app, & install & refresh page where I wanna DL an video, & it still continues to endlessly give me the above msg. It just goes in circles & never accomplishes anything! It USED to work in older versions of the browser, but sadly no long does in newer versions for unknown reasons! Fix this already, would you guys?!
