Changing the User Agent, a New Google Chrome Feature

Changing the user agent of a browser is sometimes helpful if you're visiting a site that doesn't work well in your browser or if you're a developer and you want to test a site. Until recently, changing the user agent required installing an extension, opening about:config or adding a command-line parameter.

Now that browsers started to include powerful developer tools and even Internet Explorer has a built-in user agent editor, Chrome added a similar feature. It's only available in Chrome 17 (Dev Channel / Canary) right now.

Here's how to change the user agent:

1. open the Developer Tools (Ctrl+Shift+I on Windows/Linux, Command - Option - I on Mac OS X)
2. click the "settings" icon at the bottom of the window
3. check "override user agent" and select one of the options (Internet Explorer 7/8/9, Firefox 4/7 for Windows/Mac, iPhone, iPad and Nexus S running Android 2.3). You can also select "other" and enter a custom user agent.

  2. My Chrome on Windows 7 is up-to-date and the only option I have under Network is "Disable cache".
    Also of note, the icon I have is a gear, not a wrench.

  10. Hi
    I recently published on the Chrome Web Store a Chrome 17.x extension which allows you to modify the User-Agent on a per-tab basis.

  11. Well finally there is internal tools for that. Still some mobile sites detects resolution and scales the webpage for the screen resolution.

  12. This does NOT work on the current public release of Google Chrome (16.0.9 as of 2012/01/09). Looks like a useful feature, can't wait until it's generally released, but until then I have to keep my chrome version the same as the real world...

  13. Surprised Google took so long to include this feature. There is an extension available but it rarely works on my Ubuntu installation.

  14. I've found that it works for the page it is on, but if you link to another page, the user-agent information is lost, and you get the desktop version of the site. Using Chrome 17.0.963.79

    1. This is why n00bs like you... eh... chupa. You should have read Anonymous' comment above before entering the firefox pissing contest. It doesn't work on newly accessed pages... I've checked through an html packet sniffer from my LAN card's buffer. Firefox still owns Chrome in this regard, you still need a different approach for Chrome to work.

  16. I'd like to set the user agent as Googlebot. I tried to type in Googlebot2.1 and each of the three strings I could find:

    Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
    Googlebot/2.1 (+http://www.googlebot.com/bot.html)
    Googlebot/2.1 (+http://www.google.com/bot.html)

    None made it. What should I insert? Or should I do anything else than copying the string and pressing enter?
