Mozilla’s Web development tool Firebug is getting a facelift in version 2.0. The latest release not only comes with a new theme and a clean user interface, but it also is getting a new debugging engine.
“Firebug 2 introduces many new features and bug fixes also because we completely removed dependency on the ancient Firefox debugging engine (a.k.a. JSD1) and incorporated a new debugging engine known as JSD2,” wrote Jan “Honza” Odvarko, Firebug’s lead developer, on its website.
Firebug is an open-source project that integrates with Firefox to allows users to edit, debug and monitor CSS, HTML and JavaScript live on any website.
