The Firebug Tracing Console (short FBTrace) is used for debugging Firebug and Firebug extensions. It logs all Firebug activities and thereby helps tracking down errors inside the source code.
Until Firebug 1.7 FBTrace was bundled together with its alpha and beta versions. To be able to inspect the logs even in the case Firebug is broken (e. g. it doesn't even load itself) and to make the release process easier for Firebug 1.8 FBTrace was extracted from the Firebug source and is now available as an independent extension. For more information about this step please read the news group thread about FBTrace as well as the blog entry to Firebug 1.8a1.
The simplest way how to install FBTrace extension is to use an XPI we regularly build from the source. Check releases directory for the latest version.
You can get the FBTrace source using a Subversion client. To install FBTrace please follow the description of building Firebug from source or place a file named
email@example.com containing the path to the source code in your Firefox profile directory (for more info on how to do this please read the steps to create a Firefox extension proxy file).
