In the video I show how to first save a bookmarklet generic and then make changes with the javascript code copied to the download page, this is done I go to YouTube to see a video but the first step to the Desktop mode, once you open the video I type the initial bookmarklet on the address bar to retrieve it and run it at this point the bookmarklet runs correctly showing the download link.
This technique is the only one to install bookmarklets, simple and intuitive to use on Smartphone and Tablet for any bookmarklet.
