mozilla-adblockplus won't build in EL6. I suspect the version of python-jinja2 is too old. My question: The upstream XPI for mozilla-adblockplus includes a JAR file. This JAR file contains _no_ libraries or binaries. It only has images, javascript, and some XUL files. Definitely no Java, despite the JAR extension. It appears to me that there are three options. Option 1: Unpack the upstream XPI and ship that. Option 2: Figure out how to make this package build, if it can at all. Option 3: Retire the package. AdBlock Plus 1.x will be disabled by default in Firefox 10 without disabling addon compat checking, and I'm not even sure it will work at all.
