This page describes how to preview your project in a web browser.


You can preview a project either in a new web browser window or in the Preview pane of the Aptana HTML Editor. The instructions below describe both options for previewing a project.

Previewing in a separate web browser window

To preview your project in a web browser, click the Run button in the toolbar. This launches a preview of the current web page in the Aptana editor.

By default, the current web page opens in Internet Explorer on Windows or Safari on OS X. To change which web page opens in the browser or to switch the default browser to Firefox or another browser, you can change your browser configuration. See Setting up your web browser configuration for information on changing your configuration.

To preview a project in a web browser:

  • To switch configurations, click the downward-pointing arrow just to the right of the Run button , and select a configuration from the menu.
  • If the default behavior opens the wrong URL, you will need to create a new configuration. To learn how to set up additional configurations, see Setting up your web browser configuration.
