Very useful extension, I don't quite understand why this feature was removed to begin with.
I was able to make it work with the production version of 3.0 by downloading the .xpi file, unzipping it, editing the install.rdf file (change the maxVersion in line 14 to 3.0), creating a new XPI, and installing it. Do this at your own risk, of course.
