Random User-Agent for Chrome and Firefox 4.2.1

Random User-Agent for Chrome and Firefox replaces the original browser User-Agent identifier with one that is randomized.

Random User-Agent helps to stop data leakage. It automatically replaces User-Agent strings after a specified period with a randomly selected one. User-Agent strings can also be set manually. The extension is lightweight, using very few resources. User-Agent randomization can be customized (what browsers and OS are spoofed, etc.). An exceptions list is available, including wildcards. Random User-Agent also helps to protect against Javascript exploits to hide your identity and protect your anonymity.

A User-Agent is a string that is sent to any website you visit; this is a sort of fingerprint your browser leaves behind containing:

The name and version of your browser;
The name of the operating system (Mac, Windows, Linux, etc.) and its version;
Information about some of the plugins installed on the browser;
Other information that identifies and exposes you.
