Essential Google Chrome about pages

Google Chrome about pages

Like most other browsers, Google Chrome has some special pages that show information about memory usage, cached files, plug-ins and more. Here’s a list of the most interesting about: pages available in Google Chrome (you can open them by dragging about:name to the address bar). These are about all the chrome about pages I wished to share with you.

1. about:version – Google Chrome shows the version number the browser, WebKit and V8 (JavaScript engine). You can also find the user-agent used by Google Chrome:

Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/525.19 (KHTML, like Gecko) Version/3.1 Safari/525.19


2. about:plugins – the list of plug-ins that are available in Google Chrome: Shockwave Flash, RealPlayer etc.

3. about:cache – a list of all the web pages cached by Google Chrome. The browser doesn’t have an option to limit the cache’s size, so it’s recommended to regularly empty the cache.

4. about:memory  this pages compares the memory used by all the active browsers and by Google Chrome’s tabs.


5. about:stats – a list of internal counters and timers that has a funny subtitle “Shhh! This page is secret!”.


6. about:histograms – a list of histograms for Google Chrome’s internal metrics.


7. about:dns – Google Chrome prefetches the DNS records for 10 frequently visited hostnames. This feature can be disabled in Options > Under the Hood by unchecking “Use DNS pre-fetching to improve page load performance”.

8. about:network – this page could be used for I/O tracking and it’s a partial replacement for the Live HTTP Headers extension. Click on “Start I/O tracking”, open a web page in a new tab and you’ll get a list of all the images, scripts and objects loaded from that web page.

9. about:crash – crash the active tab. Google Chrome displays the “sad tab” image, followed by this message: “Something went wrong while displaying this webpage. To continue, press Reload or go to another page”.


10. about:hang – type this in the address bar of a tab when there’s already an active web page to hang the process (this means that the process no longer accepts any signal, but it’s still running). The other tabs will continue to work and the active tab can be closed.

11. about:internets – this is an Easter egg that references two popular Internet memes:Internets and Series of tubes. Google Chrome embeds the 3D Pipes screensaver from Windows, so you’ll see it only if you have the file sspipes.scr in C:WindowsSystem32.

12. about:net-internals – A very useful backend tool that gives you access to a list of currently open connections, the ability to check what current proxy settings are in effect, and even a test tool that will try and identify why a certain page is not loading properly. Be careful with what you do here, as I could not find any documentation for it.

13. about:about – This page lists most (but not all) available about pages that you can access. In my testing, however, the links on this page are not functional despite being clickable, and you need to manually type them into the address bar. This page is one of the best chrome about pages I can think of.

14. about:flags – One of the most interesting about pages, this allows you to turn on what Google terms “experiments”, modifying various functions of the Chrome browser. Some examples are an FPS counter that displays when hardware acceleration is in use, the option to disable VSync, and the ability to enable an in-tab preview of print. I tested a couple of the experiments and found some working, while others didn’t seem to do anything. Please report your findings here.

One reply on “Essential Google Chrome about pages”

I’m impressed, I must say. Seldom do I encounter a
blog that’s both equally educative and amusing, and let me tell you, you’ve hit the nail on the head.
The problem is an issue that too few people are
speaking intelligently about. I am very happy that I came across this during
my hunt for something relating to this.
