FireBug for Firefox - web 2.0 debugging with ease
So what’s that cool about FireBug? Its Firefox extension with neat console, javascript debugger and inspector for all modern web developer’s needs. FireBug lets you explore the far corners of the DOM by keyboard or mouse. All of the tools you need to poke, prod, and monitor your JavaScript, CSS, HTML and Ajax are brought together into one seamless experience, including a debugger, error console, command line, and a variety of fun inspectors.
Features:
- Logging for web pages - ability to log messages from JavaScript in your web page directly to the FireBug console.
- JavaScript Debugging - No need to fire up a big fat debugger. FireBug includes a simple lightweight way to set breakpoints in your scripts and examine every step of execution.
- Errors at your fingertips - FireBug adds a little icon to the Firefox status bar which tells you if your page is busted. Open up the FireBug panel and you’re looking at the errors that occurred in that page, and only that page.
- Inspectors - FireBug’s inspectors let you stroll through the DOM using the familiar hyperlink model. If you see an object reference, you can click it to inspect it.
- JavaScript command line
- Ajax Request Spy - The FireBug console can log all Ajax request traffic as it happens, and allows you to inspect the responses.
