Coda's built-in Preview uses Safari's WebKit engine. To preview in another browser, choose View > Preview In and select from the list of currently installed web browsers.
Coda's preview updates on-the-fly for static pages (such as plain .html files). If your page requires server-side processing, or uses a dynamic scripting language such as PHP, you must configure a Site in Coda with the appropriate remote root URL. See Using sites for more information.
If you are developing a dynamic site using a local server environment (such as MAMP) you can set the Site's remote root URL to be relative to http://localhost to get previews.
