Editor’s note: today the Firebug team released Firebug 1.5. Check out Rob Campbell’s announcement reposted below.

I am very happy to be able to announce the release of Firebug 1.5.0 on addons.mozilla.org. This release represents a significant effort by the Firebug Working Group which saw the addition of some new faces over the last few months.

Here’s a quick run-down of some of the new features:

  • Enhanced Inspector
  • More accurate Net panel timings
  • Break on HTML mutation
  • MathML and SVG namespace support
  • Break on XHR
  • Improved HTML editing
  • Persist buttons on Console and Net panel
  • Separate Computed CSS and Style subpanels
  • Many many bugfixes and stability improvements

This is a huge release and these are just some of the highlights you’ll see in this new version. Please feel free to read the Firebug 1.5 release notes and John Barton’s blog post for more details.

As always, if you encounter any problems, don’t be shy about filing a bug! We’ll be following up with quick point-releases if and when you find issues.

Special shout-outs and thanks to Mike Ratcliffe for the Inspector improvements, Steven Roussey for HTML editor improvements, SVG and MathML namespace patches, Honza for being awesome and John Barton for his tireless contributions.

    Thanks! I must admit (using a wee bit of exaggeration) that my life wouldn’t be the same without Firebug.
