# Previewing a project in a web browser [edit]

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

## Introduction

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.

## Instructions

### 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 or Safari on OSX. 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 use the default configuration or the last configuration that you used to view the project, click the Run button .
- To switch configurations, click the downward-pointing arrow just to the right of the Run button , and select a configuration from the menu. (To learn how to set up additional configurations, see Setting up your web browser configuration.)

Aptana opens your project in a new web browser window.

### Previewing in the Preview pane

You can also quickly preview a web page for an open HTML file by clicking the Preview tab at the bottom of the Aptana HTML editor. This displays your page in the embedded web browser.

By default, the Preview tab uses an embedded IE browser (or Safari on Mac OS X). To add the Firefox browser as a Preview option, see Adding Firefox support to the Preview pane.
