Google Chrome Frame was a plug-in designed for Internet Explorer based on the open-source Chromium project, first announced on September 22, 2009.

In a test by Computerworld, JavaScript code ran 10 times faster with the plug-in on Internet Explorer 8.

The newer Chrome Frame installer ran at Admin level by default and fell back to Non-Admin mode if the user didn't have the necessary permissions on their machine.

[6] For a blanket rollout on an entire web site, an Apache server with mod_headers and mod_setenvif enabled can specify a header directive like this: Internet Explorer add-ons do not function on pages rendered using WebKit.

With Google Chrome Frame installed, users can add the gcf: prefix to URLs to render them with WebKit and V8 instead of Internet Explorer's built-in Trident engine after enabling this feature via a registry setting.
