Firefox Forget button
This is more of a stripped down version of the Clear Recent History feature, this button when you click on after selecting a time frame, deletes recent cookies, history and closes all tabs and Windows and opens a new clean window.
And Forget button in new window shows a dialog with text ‘your recent history is cleared. Safe browsing! Thanks!’.
