Add a "?" besides setting that could help fingerprinting you if changed
An interactive GUI "What not to do" guide that explains what should be avoided.
A "(?)" beside a setting should explain what happens if you, for example. Remove all the Search Engines from the list, if that could create a unique fingerprint. Or changing the Default Search Engine.
I recently figured out that the Bookmarks Toolbar was changing my Window Size without me knowing. That I have been using on websites for months. Changing the Bookmarks/History to a popup window would be better maybe? Or simply have the blank page after opening a new tab contain all your bookmarks.
