Firebug 1.6a18

getfirebug.com has Firebug 1.6a18, the don’t-plan-beta-releases-in-summer release.  The major new feature here is ‘switch to default locale‘, support for en-US user interface labels even if you are running on a localized version of Firefox.

12 more bugs fixed.

All of our tests pass on Firefox 3.6.8, so we are hoping that the Firebug automatic testbot will begin to show us “green” for 3.6 once we get it updated to 1.6a18.

Firebug 1.6a17

getfirebug.com has Firebug 1.6a17. We’re aiming for b1 next week, and this time we mean it!

New in this release:

  • First run page comes up on install or update.
  • Removed all the .DTD files, no more entity based localization.
  • Console panel filtering buttons (error, warning, info, debug).
  • Stack side panel for Script panel shows function argument names and values.
  • More tweeks for command line completion.
  • Script panel shows nicer message when it is inactive during page load.
  • Changes to allow Firebug to work in Firefox 4.0b2pre (still many issues).

This release is dedicated to nkjoep for helping find the cause of issue 3200, a serious bug that only surfaced when an uncommon option is used.

The release also has lots of locale updates and bug fixes.
