What it does
Firefox Focus is a dedicated privacy browser that blocks common trackers and provides an erase button for browsing history, cookies and passwords.
Focus suits the quick lookup you do not want to keep as a continuing browser session. Its erase button clears the history, cookies and passwords described on the product page. Automatic tracking protection is also part of the default experience.
You can pin up to four shortcuts for frequent lookups. Focus is most useful as a place for disposable browsing sessions, while a full browser can keep the tabs and persistent logins you actually need. Clearing local session data is different from concealing a network connection or hiding activity from a website you sign into.

- Direct erase control for session data
