Adobe BrowserLab enables cross-browser testing by producing screenshots of websites from various web browsers across different platforms (Windows and OS X are currently supported). Compare screenshots side-by-side or overlaid upon one another, and utilize diagnostic tools to help discover cross-browser differences. The service can access dynamic pages across the web, or viewed locally via Firebug or Adobe Dreamweaver CS5. BrowserLab is updated frequently to enhance the service and provide access to a fresh and relevant set of browsers.
