With this add-on, you can save the current URL in the ".url.download" file and take screenshot of visible Tab. Starting with the 112 version of firefox, the name of the saved file should not contain the ".url" file extension, so the ".download" ending is added to the ".url" extension. URL is stored in a lightweight version InternetShortcut file without images and links on the favicon. Only URL. The default save folder is "downloads".
