Extensions, plug-ins, add-ons, whatever you want to call 'em, Firefox 3 has 'em. In fact, though it may seem that many of your favorites haven't yet updated, you might be in luck. By visiting the home pages of several of the plug-ins I use, I found that most of them had either a functional, stable beta or a full update ready to use with Firefox 3. This collection of add-ons I use both at home and in the office, and can be used for the Windows, Mac, and Windows Portable versions of the browser.
