It's easy to check what plug-ins you already have on your computer.

First, figure out what kind of computer you're using. It should be either a PC or Macintosh. Then find out which Web browser you use–Internet Explorer or Netscape. If you use the America Online browser, see the AOL Information page.

Note: To see if you have JavaScript turned on, see the Test the Plug-ins page.
