  4. Choose what you want to clear from Firefox

    As you browse the internet, Firefox keeps different types of data related to your activity. It's not necessary to completely clear all your browsing data in Firefox; for example, it's possible to choose to only delete the cache, or just the History (list of URLs), or just the Cookies, and so on.

    In the Clear Private Data section you will see a number of controls to select which types of data Firefox will clear. You can choose which ones to clear by sliding the various controls to the right to mark them to be deleted.
