Google Chrome, like FireFox, has special commands, the about: commands, to show relevant information about the browser.
Here are some of them:
about:cache - Every single url that you visited.
about:dns - A list of used DNSs and response times.
about:histograms - Some text histograms with performance measures.
about:internets - Shows the tube screensaver of windows in the tab. The title shows: “Don’t Clog the Tubes!”.
about:network - shows url information about the current request(s) you are making.
about:memory shows how much memory google chrome and each tab that is open is using. If you have other browsers open it also shows their memory consumption.
about:plugins - a list of all plugins currently installed.
about:stats - a list of statists of the browser. Just a bunch of counter and timers. In the top you can read: “Shhh! This page is secret!”. Google guys have a sense of humour.
about:version - current version information featuring a big google logo (like we didn’t knew that chrome belonged to google).
And finally the “piece of resistence” and my personal favorite,
about:crash - crashes the current tab and shows the sad smile:

E ainda:
about: (equivalente ao about:version)
about:hang
about:shorthang
