Clear Browsing Data Except Kept Sites

About this product

Clear Browsing Data Except Kept Sites is a lightweight, open-source extension that removes the history entries, cookies, and site data of every site you have not chosen to keep. Add the sites you want to stay signed in to and remember on the settings page, then turn clearing on. Each time Firefox starts, the extension clears the history and cookies of all other sites. You can also clear on demand with Clear Now.
