Firebug 1.12 beta 2

Firebug team released Firebug 1.12 beta 2 (archive).

It’s our second beta and we would like to encourage Firebug extension developers to test with this version. It’s solid and we are willing to help with testing and fixing any problems that might appear. Firebug 1.12 final is planned within a month or so.


Firebug 1.12 beta 2 fixes 12 issues
Firebug 1.12 beta 2 is compatible with Firefox 22-25

All users subscribed to the AMO beta channel will be automatically updated. See the Development Channel section at the bottom of the page.


A highlight from this release

  • Toggle Visibility of Side Panels (issue 6095)
  • One little enhancement yet sneaked into this version. You can now toggle visibility of side-panels. See couple of screenshots.

    Side Panels Expanded

    For example, if you don’t need the Selectors side panel you can keep it hidden.

    Side Panels Collapsed


    The state is persistent across Firefox restarts and it’s panel specific. So, if you hide side panels for the CSS main panel it applies to the CSS panel only.


  • The Console panel does *not* activate JSD (issue 4978)
  • This is great performance improvement. The Console panel doesn’t require JSD anymore (the internal Firefox JS debugging engine). If you enable the panel – JSD doesn’t have to be activated. This change makes the Console panel faster.


Please post feedback in the newsgroup, thanks
