Netscape Gecko User Agent Strings

List of released user agents based upon Netscape GeckoTM

Appropriate use

We do not recommend using User Agent Strings as your primary means of browser detection. See Browser Detection and Cross Browser Support for an in depth look at various approaches to browser detection with recommendations.

In particular, we recommend only using User Agent String based detection for server side browser detection. If your existing client side browser detection code uses User Agent strings, you can simply search for the string "Gecko" in the User Agent in order to detect any Gecko based browser.

For all Gecko detection issues which deal with specific bug fixes or which require knowledge of specific vendor strings or build dates, use the navigator object.
