I'm not an Ubuntu developer yet, but I packaged this package with XPI.TEMPLATE and mozilla-devscripts. The packaging totally differs from the Debian's package, so I think that most of the changes in version 0.3-1ubuntu1 shouldn't be mentioned. The only change from that version that should be mentioned is the modification of Maintainer field according to DebianMaintainerField spec, which Nathan did.

So, these diffs look fine to me.
