[Feature request] Automatically delete cookies, cache and history when closing

[ghost]

In Firefox you have the option to automatically delete cookies, cache and history when you end a session. I know that it's not implemented in Chrome, and probably not in Chromium, so maybe that's the reason it's not implemented in Morph.
I don't know how much Morph borrows from Chromium, but would it be possible to add this feature ?

Thanks !
