Now that you mention it... The package contains a single shell script, "source included", however, in case you really want to rebuild the .deb, I uploaded the source to the same directory. Our package moves /usr/lib/iceweasel/iceweasel to /usr/bin/iceweasel/iceweasel.real and replaces the original script by an additional wrapper script. Which is "not the right way", as one Debian maintainer noted, but it happened to make things a lot easier for support in our project.
