SWF - Run in Browser
The .swf format can be viewed by dragging the saved file into a new Internet browser tab on Windows or Mac computers. The browser will need the Flash plugin installed and enabled.
You may get a security warning running a locally saved .swf in a browser (like Internet Explorer, Safari, Firefox or Chrome).
See Flash Security Settings for more details. You may have to refresh the page and/or give the page permission to run before you see anything.
