Making sure your site appears as it should in different browsers is no mean feat for the people who code your website.
It is always wise though to check your site in as many browsers, including mobile browsers, before it goes live.

Netrenderer – for all the most recent versions of Internet Explorer (IE)
Browsercam – cross browser compatability on a wide variety of devices.
