Why single out Kiss Metrics? One example, I visited Fox News last month and found they set up an HTML5 database called, in a rather unsubtle choice, "evercookie". I can't confirm that this is the case currently, though since the ability to view HTML5 databases in Preferences seems to now be missing from all the browsers I have (which seems odd, too!).

I imagine it is named as such because they are using evercookie[1], off the shelf.

In Chrome you can bring up the Developer Tools (View menu on the mac, I think it's in the wrench menu on other platforms). You can see databases, cookies, etc. in the Resources tab.

"Evercookie" is more than just standard browser cookies: http://en.wikipedia.org/wiki/Evercookie

Thanks, I see that in the Inspector now.

I recall menus in Safari, Mobile Safari, Firefox and Chrome which listed all the databases stored, along with the name. It was in Preferences near the cookie and password management.

It looks like the 'databases' menu is no longer in Mobile Safari preferences, and now Safari 5.1 will tell you what a website is storing in general terms, but no longer details the individual databases in preferences.
