When you access a website, your browser sends a string called the User Agent containing your browser's name, operating system, and other technical metadata of your device. Unfortunately, this metadata is often abused by trackers to build a fingerprint of your system and uniquely identify you throughout the web. To limit the efficiency of fingerprinting you can install a random agent switcher which periodically changes your browser's user agent, making it harder to uniquely identify you.

Warning: Using an agent switcher may cause some pages to display incorrectly or not at all. To prevent this behaviour, we show how to disable the extension in such cases.


Like any other add-on, install Random User Agent by visiting the Chrome Web Store and clicking on Add to Chrome (Fig. 1) and then clicking on Add extension when prompted (Fig. 2).

Upon successful installation a notification appears on the top-right corner, and the Random User Agent icon is added to your toolbar (Fig. 3).

To check you currently assigned user-agent, click the icon (Fig. 4). If you stumble on a page which breaks when you have Random User Agent enabled, you can either disable it for that domain, clicking on Enabled on this domain, or pause the switcher temporarily, clicking on Pause Switcher.

Random User Agent is configured by default to change the user agent every 10 minutes, although you can configure this in the settings (Fig. 5).
