Just installed TB3.0a1 and javascript_debugger-0.9.87.3-fx+tb+sb+sm.xpi.

Opening any source produces the following error:
XML Parsing Error:
Location: 
x-jsd:source?location=chrome%3A%2F%2Fcommunicator%2Fcontent%2FcontentAreaClick.js&instance=26
Line Number 2, Column 1:<?xml-stylesheet type='text/css' 
href='chrome://venkman/skin/venkman-source.css' ?>

Any advice how to work with both??
