Firebug 1.12 alpha 3
getfirebug.com has Firebug 1.12 alpha 3
Firebug 1.12a3 fixes 11 issues
Firebug 1.12a3 is compatible with Firefox 18-22
Some highlights from this release
- New Net panel filters (Issue 6025, Issue 6273)
- Help in the Command Line improved (Issue 6200)

The old Flash filter has been renamed to Plugins and covers Flash as well as Silverlight HTTP requests. There is also a new filter labeled Fonts that is used to see HTTP requests for custom fonts only (font/ttf or font/woff mime-types).

The help command (available in Firebug Command Line) has been extended and displays also some useful tips for the Command line itself. So, apart from the Command Line API section (which was already available before) there is also Command Line Tips section. You can learn about how to inspect closure variables directly from the Command Line.
Please post feedback in the newsgroup, thanks
