If you spend a lot of time accessing Google services in Firefox, GButts is an add-on that can save you a few seconds of valuable time. Basically, the add-on includes links to virtually every Google service including Gmail, Google Maps, Google Docs, Picasa, YouTube, Orkut, and Google Voice.

You can configure GButts to either show some or all of these bookmarks in your browser's navigation bar or you can just create a single Google icon that provides a drop-down menu with links to your favorite Google web applications.
