Firebug 1.3 released

“Honza has made some fantastic improvements to the Net panel. John Barton has improved the Script panel and debugging features as well as tweaking the console. Maybe more significantly were some of the changes under the covers. The new Tracing panel (FBTrace) for debugging Firebug itself during development is a huge improvement over the previous console-based system. We’re starting to get some unit test coverage through John Resig’s and Honza’s FireUnit.”
