QuickDrag is a Firefox extension that extends the function of the drag-and-drop mouse gesture so that it can be used to load URLs, do a web search of selected text on a page, or save an image on a page—all with a simple drag-and-drop.

QuickDrag is based on the defunct Super DragAndGo extension.

Select some text on a webpage and then drag-and-drop it anywhere to search for the text in a new tab using the Firefox search box's currently-selected search engine.

Select something on a webpage that looks like a URL and then drag-and-drop it anywhere to open the URL in a new tab.

Drag an image on a webpage and drop it anywhere to save the image.

I have compiled an overview and F.A.Q. to help explain the goals of QuickDrag and how it differs from other similar extensions.

  • Added an option to open a dragged clickable link (i.e., <a href=…) in a new tab instead of searching for the text or saving the image. This will allow users who lack a middle mouse button to use drag-and-drop as a replacement for the middle-click.
  • A Referer is now included in the HTTP request headers when saving images. Note that embedded images already send a Referer when they are loaded, so sending one when they are saved does not send any extra information to the server that had not already been sent. This will eliminate problems with saving out-of-cache images residing on servers that perform anti-leeching Referer checks.
