One of the first things I noticed about Chrome was the lack of the special page “about:config”. I used it extensively in Firefox to tweak settings. Google Chrome does have a few special pages. Here are some hidden features I’ve run across.
about:plugins
If you’ve installed a plugin – or you think you have and you want to see if Chrome is actually using it, this is the page for you.

about:memory
This page shows memory usage with a breakdown of what each tab is using. It also includes memory usage of other browsers for comparison.

about:cache
Here you can load a page or image you have cached, or just see what’s in your cache.

about:version
Typical about dialog. You can actually load this page without the word “version” after the colon.

chrome://newtab
Although it’s much easier to hit CTRL+T or right click and click “New Tab”, you can also open a new tab using this url.
The only use I see for this one is when you want an icon to click that opens Chrome with an empty tab, ignoring the default that might be to open to a specific homepage.
