Version 2.0 of the popular open source Firebug Web development tool, released this week, features a slew of programming improvements, including debugging enhancements, syntax highlighting, and better code auto-completion.
The debugger is the heart of Firebug 2.0, and its features are integrated throughout the tool, Firebug team leader Jan Odvarko said. "Firebug's debugger is now based on new debugging APIs -- known also as JSD2 -- that are more stable, faster, and consume less memory."
The tool's Script panel supports syntax highlighting, and Syntax coloring is also offered for HTML and the CSS source edit mode. Code autocompletion, which works for HTML, HTML style, and SVG attributes, is now available in the Command Editor within the console panel.
Firebug's builders collected feedback from developers and designers and used the feedback to tweak features in this release. "Firebug's strength is mainly its user interface and user experience. It's simple and intuitive, a handy tool," said Odvarko. "Other built-in tools introduced in, [for example,] Firefox, Chrome, and IE (Internet Explorer) might have more features now, but the user experience of those individual features is often [a] step behind Firebug."
Introduced in 2006, Firebug has been downloaded 70 million times. It's compatible with the Firefox browser, registered as a Mozilla trademark, and maintained by a group of developers around the world. Version 2.0 is downloadable at Mozilla's addons website.
