Firebug 1.12.8

The Firebug team released Firebug 1.12.8. This version represents a maintenance release fixing compatibility issues with upcoming Firefox versions.

 

Firebug 1.12.8b1 has also been released to update users on AMO beta channel. This version is exactly the same as 1.12.8.

 

Firebug 1.12.8 is compatible with Firefox 23 – 30

Firebug 1.12.8 fixes 2 issues.

 

JSD1 vs. JSD2

This release is solving a compatibility problem related to the JavaScript Debugger Engine API (JSD) in Firefox. This API is going to be removed from Firefox 31 and any extension that is using it (including Firebug) needs to switch to JSD2 that has been around for a while.

The JavaScript debugger in Firebug 1.12.8 is based on the (old) JSD API, so the Script panel will be disabled if you’re running this Firebug version on Firefox 31.

The Script panel displays a message explaining why it’s disabled and a link to the Firebug 2 page. Firebug 2.0 is fully based on JSD2. Firebug 2.0 requires Firefox 30 as the minimum version and all users running it should check it out. Even when Firebug 2.0 is not finished yet, it’s already quite stable.

 

Here is a quick compatibility table:

  • Firefox 23-30 with Firebug 1.12.8
  • Firefox 30+ with Firebug 2.0 beta 1

Please post feedback in the newsgroup, thanks.
