Firebird Extension / Theme RPMs

If someone can provide a mechanism for programmatically installing Mozilla Firebird extensions, I would be more than happy to put a night aside for packaging a bunch of them for RPM to push up to fedora. From what I’m reading here, it looks like the xpinstall stuff is limited/non-existent from the command line. Lots of people wanting to know how to do unattended/cli installs but no one replying seems to understand why you would want to go cli instead of using the browser. Trying to roll Firebird out to a large number of machines w/ a standard set of extensions is a nightmare.

Right now I’m thinking I may have to resort to installing the most common extensions on one box and blow tarballs. These boxes are somewhere around 99% managed by RPM so slapping unmanaged crap into /usr/lib just kills me.

I have a few things I would like to try before giving up. This post looks promising but it’s dated 2000-01-02. If any mozilla-savy person out there could hack up a nice little xpi install app it would be much appreciated.
