# Web Development Tools

For web developers, &brandShortName; provides several tools to aid in developing and debugging web applications. Some of these are optional installs. To access these tools, open the Tools menu and choose Web Development.

- Error Console: a console window that reports problems with JavaScript and CSS code in web applications and the &brandShortName; application itself. By default, CSS parsing errors and JavaScript errors are displayed. The console can also be used to display logged messages from XUL and JavaScript code.
- DOM Inspector: a tool that can be used to inspect and edit the DOM of any web document or XUL application.
