I've been using Aviator secure browser for a while which insists that you run private mode by default (cookies and history wiped after every session), which makes me wonder how secure the history is in other browsers? Is it really necessary to wipe your history since nobody except you should have access to it or does your browser share your history with sites you visit, like it does with cookies?
So I guess my question is how vulnerable your history in your browser is for outside attacks. Is it private (only viewed locally) in most cases?
