Cookies of the Mozilla browsers have some drawbacks. So it is important for a user to know the correct method to delete the cookies in Firefox. You need to click the menu button and click the Library option. Visiting the History tab you need to set the “Time range to clear” to everything. Now you need to click the arrow button which is lying at next to the “Details” option. Select cookies clear then and close the “History” page. If you are unable to do this you need to call the Mozilla Firefox Support phone number 1-888-664-3555.
