unfortunately, the extension doesn’t offer control over UA strings used by JavaScript, like User Agent Switcher does. Therefore, the extension is useless for sites which use JavaScript to determine the User Agent (like Google Maps and many others). ---- I believe this is why facebook is not showing exactly the same as when using User Agent Switcher. With this add it appears all messed up. Perhaps the lack of javascript is what is causing it. If author could fix this it would be perfect. This script has become very usefull for showing facebook without the disgusting Timeline feature. You just set it to use IE7 and facebook appears without Timeline.

This review is for a previous version of the add-on (0.1.3.1-signed).
