Google Chrome's 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).

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:\Windows\System32.

  1. I pressed Ctrl+U (view source) while viewing the "about:crash" page, and Google Chrome crashed (the standard Windows error "don't send the report to Microsoft") after having asked me whether I wanted to reload the page because of a problem.

  2. I can't reproduce your problem, but here's another way to crash Chrome: type in the address bar :%

    I got the same error message when I tried to type :% in the address bar and when I pressed Ctrl+U on the crash page: Google Chrome is blocked. Restart now? (maybe not exactly this since mine is in French).

    I found a way to reproduce my bug with the source of the crash page. You have to avoid opening a new tab and then typing "about:crash". To crash Google Chrome just follow your tip: drag about:crash not in the address bar but on the "new tab" (+) button after the last opened tab. And then just try Ctrl+U, it should crash.

    1. That no longer causes a crash. I'm glad it's fixed. Don't really know how long its been fixed, but it's been 4 years since your post. If this was IE, four years later IE would still be the same version and still have the same error. So, good job Google, now stop showing crappy advertisements on my Phone!

  7. Why does Chrome use the IE settings for connection ?


    I have FF as my default browser and had switched off proxy in IE and FF but not in chrome. I switched on the proxy in my FF but not in IE. ( and did not change chrome settings at all) When i started chrome, it was not connecting. Found out the settings for connection and lo the IE connection settings pop out of chrome.

    So why is chrome riding on top of IE setting ?

  8. Damned, my version is already outdated ?

  14. Heu.. Google has forgotten the RSS or I am stupid???

  15. Did you forget that this is Google Chrome 0.2, not Firefox 3 or IE 8. For this initial release, Google wanted to create a solid foundation for the future. Features like previewing feeds, organizing bookmarks, customizing the interface will come later.

    ReplyDelete
  16. Totally agree the last Alex comment.

    As a browser framework, I found Chrome as a really good start !

  17. I hate all your Chrome stuff. If Google was serious, they'd release Mac and Linux and Windows versions all at the same time.

  23. The User-Agent clearly varies. I get : "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.2.149.27 Safari/525.13"

  25. @thampan

    You can provide an own proxy server for Google Chrome using the command line argument "--proxy-server=PROXYSERVER:PORT"

    So Chrome will not more depend on IE proxy settings.

  27. For the case of http://www.taskwriter.com, Google Chrome is faster about 9 times than IE 6, but still in the same range as Firefox 3.0. See the grapsh here : http://www.taskwriter.com/blog/how-good-chrome-really-is
    For the real case of http://www.taskwriter.com, Chrome is a bit faster than Firefox 3.0. The graphs here http://www.taskwriter.com/blog/how-good-chrome-really-is

  28. The "--proxy-server=PROXYSERVER:PORT" command line switch does not seem to work since Chrome v149.27.

    I've tested using 149.29 and 149.30 running in Vista and under wine in linux.

  31. I need some HELP!! I am currently using Google Chrome 0.3.154.9 with my Windows XP Home Edition Version 2002 Service Pack 3 and when I am at work, which is an on-line UK bingo site hosted by Virtue Fusion I get many Shockwave Flash error messages. I am also using macros with KeyBoard Express 95/NT Version 2.6a only when I am working. Although I can x out the error message and hit f5 and be brought right back in the rooms it is VERY annoying and I was wondering if there was a solution to this at all..? Hope to get some helping responses :)

  34. Assuming the proxy requires authentication (as in my workplace), is there a way to provide this with command line arguments, I'm not worried about the password not being displayed in the encrypted form "--proxy-server=PROXYSERVER:PORT", how would I provide a username/password@proxyserver command with this? Is it possible? thanks, issue is that each and every tab prompts for this, and is quite irritating. Chrome remembers the username and password but forces me to click the login button.

  40. Is there an easy way to cusomize Google Chrome's home page or bookmark bar location?
    I'd like to show more than 9 frequently viewed web pages, and I'd like to move the bookmarks bar to a column in the white space on the sides of most pages. Is there a custimization utility like in firefox?

  44. Something went wrong while displaying this web page. To continue, press reload or go to another page. over and over and over and over and over and over.
    Read "Did you forget that this is Google Chrome 0.2, not Firefox 3 or IE 8." Does this mean the toaster won't make toast? What a load of crap.

    ReplyDelete
  45. Oh well, guess I have to go back to firefox. as cumbersome as it sometimes is, it always works. Not so with chrome.

    ReplyDelete
  46. @Kaushik - Assuming your proxy server uses HTTP basic authentication and not some more complex scheme, you can provide the username and password in the standard URL format:

    [user]:[password]@[domain]:[port]

    E.g.:

    --proxy-server jdoe:secretpassword@example.com:8080

    ReplyDelete
  47. @Katie Thanks, gave it a shot: chrome didn't prompt me for the username/password (Yah!). But when i went to google.com it didn't open up (:( boo!)

    I'm presuming my folks here at IT aren't too comfy with basic authentication?

  53. Chrome is dead, back to Firefox.... I've run anti virus, cleaned browser history, uninstalled and reinstalled...still the same msg over and over on every tab

    Something went wrong while displaying this web page. To continue, press reload or go to another page.

    I have the latest version as of 4/29/2010 ...Chrome seems like junk so far...flash in the pan.

    ReplyDelete
  54. You're probably using security software that blocks Chrome (most likely, a firewall). Maybe the software you're using is not very good or it's not up-to-date, so you shouldn't necessarily blame Chrome.

  60. @Thampan - Chrome does not use IE's internet settings, it uses the native OS internet settings, which happen to be the same ones that IE uses on Windows, thus you see the same box, but is Windows' settings, not IE's.
