Firefox comes with a complete Help system. To access Firefox Help, click on the "Help" menu and select "Firefox Help". It's easier than ever to find information online. Enter a search term in the Search bar and receive immediate answers from the search engine you've chosen. You can select a new search engine from the Search bar menu at any time.

Once you've gotten comfortable with all the major features, you can then extend Firefox with add-ons that allow you to add new features and capabilities to Firefox -- for a more personalized online experience.
