Is there an "about:config" (Firefox) In Google's Chrome?

Yes, and no. If by about:config, you mean "special page that lets you configure secret stuff, then it's there, and you can access it through about:flags.

If you want the complete list of pages available on Chrome, try about:about.


Using about:about converts to chrome://about which consists of ALL settings pages available for Chrome:

chrome://about page


On a Google Support forums question entitled "Is there an about:config", on July 10, 2009, user "PatrickB1991" responded with the following:

No, currently there is no about:config page...

and hope it will get implemented sometimes.
