Clear Browsing Data is a Firefox extension which enables you to delete browsing data, such as cookies, history and cache, directly from the browser toolbar. The toolbar button can be configured to clear all browsing data with a single click, or to show a list of data types available for clearing. The continued development of Clear Browsing Data is made possible thanks to the support of awesome backers. If you'd like to join them, please consider contributing with Patreon, PayPal or Bitcoin.
