It's not inherently obvious where to clear the cache and browsing history in Google Chrome. In Firefox you can go to it directly by selecting: Tools -> Clear Recent History...

It's a little less direct in Chrome. Click on the wrench on the top right of the browser -> Options -> Under the Hood (tab) -> Privacy (heading) -> Clear browsing data... (button).

Alternatively you can bring up the [Clear browsing data] option window by typing:

Ctrl + Shift + Del

This shortcut works in both Chrome and Firefox.
