One of the greatest strengths of the Firefox web browser is its extensibility. This does not only include new features but also security enhancements that make the web browser more secure and less prone for attacks and privacy breaches.
The following list will contain Firefox add-ons that protect the user from various threats on the Internet. They have been divided into the categories Browsing, Cache, Cookies, Identity & Privacy, Passwords and Misc. Each link will lead to the Mozilla homepage that contains additional information and download possibilities.
All but one add-on should be compatible with the latest version of Firefox 3. Some of them are experimental add-ons that require an account at the Mozilla website before they can be downloaded and installed.
