Incognito or private browsing really awesome featured for any browser for keep safe your all information. And incognito very much safer rather than using some Anonymizer tolls. Which will work something like that Incognito. If you used Incognito tab for browsing any website your page will be auto deleted around your browser history, cookie, cashed history after closing this tab.
It is helping very much to protect your browser history against fraud or hacker.
So, my suggestion, if you need to access your personal and importance website or email in public or office computer, do not forget to use Incognito or private browser.
