When customizing the toolbar, Firefox has a standard button named "Forget" which lets you easily delete browser data (see the attached image).
I'm using this button, but I should like the button to work in a different way. What I want is that everything except from browser history is deleted, when I click the forget icon. It should not be necessary to first click the forget icon, and then "Forget!" (as in the attached image). I don't neither want to restart the browser or open a new clean window
Does someone know how to achieve this without developing my own plugin? Does the standard buttons have some scripts somewhere that can be edited?
