Summary

Add possibility to reset the farbling key.

Setup

1. Enter a website and leave
2. Clear cookies or perform another actions that the user expects to provide a fresh state
3. Go back to the website. As the internals of the farbling did not change, the fingeprint is the same.

Expected result

The state is cleared, fingerprint changes. User is warned in a different way. Maybe there can be a button (in the popup) that allows to change the identity.

The preferred way is to sync with cookie cleaning.

Actual result/workarounds

The only way to reset farbling is to restart the browser or reinstall the extension.
