While you don't need an account to use the fast, reliable, and secure Firefox web browser, most users create a Firefox account to take advantage of features like Firefox Sync, Firefox Monitor, Pocket for Firefox, and more.
If you're leaving Firefox behind or want to start fresh with a new account, it's easy to delete your Firefox account.
These instructions work for all Firefox browser versions. When you delete your Firefox account, data stored in the Firefox browser on your computer will still exist, but it will no longer sync to your other devices.Rawpixel / Pexels
