As the subject says, Firebug 1.3.0 Final is now up on addons.mozilla.org. Release notes are here. As mentioned previously, this version will not be compatible with Firefox 3.1 (Shiretoko) and up. For that you’ll need a Firebug 1.4 alpha, soon to be dubbed beta available on getfirebug.com’s releases directory. Notes are on the releases page.

If I can babble a bit for a second, I’d like to say that I’m pretty proud of this release. 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 unittest coverage through John Resig’s and Honza’s FireUnit. And I think community involvement is at an all-time high with some excellent testing and bug reporting coming from all corners of the world. The message is getting out that Firebug is a great project to be involved in and that community contribution can really help move it forward.

So, thanks to everybody who helped out with this release. I think it’s the best Firebug yet.
