*note* 10/10 - Chameleon nightly only works w/ mozilla nightly builds
Due that Chameleon has the modern them as a dependency.
Netscape PR3 has all themes jared up, so Chameleon hangs because it is trying to link to resource urls that don't exist. Developers can easily fix this by extracting modern.jar in PR3. Or just use the mozilla nightlies which have both forms of theme bundling jar and file.
I will post an update when i get this resolved.
