You will need to install a user script manager extension to install this script.
* If you use add-ons that disable drag-and-drop such as Drag & DropZones (Web Search Pro), you cannot use features that require drag-and-drop. Please consider switching to Drag & DropZones + (userChromeJS script) if you use the above add-ons.
Features and design are referenced from Live Seeker (Distribution has ended). Icon used in the userscripts management screen is taken from サムネ職人. And, I assemble jsen to validate using JSON-Schema, favico.js to display number of hits on Favicon, and CSS.escape polyfill to apply polyfill for Microsoft Edge.
