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.

You want to clear your browsing history and cookies, but you don't want to be signed out of the websites you use every day. Clearing everything means logging back into your email, accounts and other frequently visited sites. Clear Browsing Data Except Kept Sites gives you control over what stays and what gets deleted.
Add the websites you want to keep to your list, turn on automatic clearing, and Firefox will clear the history, cookies and site data of all other websites every time it starts. You can also clear everything on demand using Clear Now. Subdomains and the parent domain cookies needed for sign-ins are handled automatically. You can also import and export your keep list, and see exactly what was removed after each cleanup.
I wanted a way to keep my important websites signed in while automatically clearing browsing data from everywhere else. Firefox offers options to clear browsing data, but I wanted something more selective. I didn't want to choose between keeping everything and clearing everything.
That idea shaped how the extension works. Clearing is off by default, so nothing gets deleted until you explicitly turn it on. Your keep list and settings stay locally in your browser. History and cookies are accessed only to decide what should be removed. There are no analytics, no tracking, no data collection, no network requests and no remote code. Your browsing data should remain yours to control.
