Firefox Security and Privacy

Firefox is among the world's safest and most secure browsers. Firefox security and Firefox privacy are covered in this free lesson.

Maintaining your privacy in Firefox

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.

Privacy settings

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.

To modify your privacy settings:

  1. Click the menu button in the top-right corner of the browser and select Options.
  2. The Options dialog box will appear. Click Privacy.
  3. From here, you can customize your privacy settings. For example, you can tell websites that you don't want your browsing habits tracked, stop Firefox from recording your history, and more.
