WP BrowserUpdate

The WP BrowserUpdate WordPress plugin shows a warning for all site visitors in case they're using a very old browser version.

It loads the upgrade JS script from browser-update.org, which sniffs out the visitor's user-agent string and shows a warning with links to various browser websites where the visitor can go download and upgrade his browser.

Installation:

Unpack and upload it to the /wp-content/plugins/ directory.
