Firefox is among the world's safest and most secure browsers. Firefox security and Firefox privacy are covered in this free lesson.
Firefox includes a range of security features, including security indicators and malware protection. Because of its advanced security features, Firefox offers an extremely safe browsing experience. Firefox also allows you to control what information you share online, keeping your personal information private.
Watch the video below to learn the basics of security and privacy in Firefox.
Whenever you navigate to a website, Firefox will display a security indicator to the left of the web address in the address bar.
Understanding these indicators can help you stay safe when entering personal information online.
Firefox offers a high level of protection from malicious websites, but you should still use your best judgement when browsing online. Review our Internet Safety tutorial to learn more about staying safe online.
Firefox takes great care to keep your personal information private. It offers many ways to control your privacy, like modifying your privacy settings, deleting your history, and browsing in a private window.
Firefox allows you to control some of the information you share online, which you can modify in your privacy settings. We recommend not changing Firefox's default selections, as they allow for the best balance of privacy and security while browsing. However, you can modify them if you want.
Like all browsers, Firefox keeps a record of every website you visit in your browsing history. You may want to remove some or all of your browsing history for the sake of privacy.
Firefox makes it easy to delete some or all of your history. For example, sometimes you might want to remove only your history from the past hour instead of removing your entire history. You might also want to remove all of your saved pages and cookies but keep your saved passwords.
For added privacy, Firefox also offers private browsing, which allows you to browse the web without recording your history or storing cookies. This is a great way to keep your browsing history secret when planning a party or buying a gift for someone who shares your computer.
Private browsing does not make Firefox more secure—it only stops Firefox from saving history and cookies for that session. Don't use a private window to view any websites you wouldn't feel safe viewing in a regular Firefox window.
