Got your attention? Don’t hold your breath, we’re not there yet, but we’re a step closer: it’s now possible to build Firefox from the Iceweasel package, since version 17.0.1-2 in experimental as of writing, 18.0~b6-1 from the iceweasel-beta repository, or 19.0~a2+20121228042015-1 from the iceweasel-aurora repository.
Before letting you know how you can get yourself a packaged Firefox based on the Iceweasel source, I’ll remind you that redistribution of Firefox packages requires a trademark license from Mozilla, so please keep the packages you build for yourself for now.
That being said, now it’s clear that such Firefox packages are not official, you can still test them for yourself. First download the Iceweasel source version of your liking, and extract it, then rename all source files from
rename s/iceweasel/firefox/ iceweasel_ should do it). Edit
debian/changelog so that the first line reads:
firefox (x.y.z-r) distribution; urgency=low
iceweasel (x.y.z-r) distribution; urgency=low
and run the following command:
$ debian/rules debian/control
Now you’re all set. You can build the package the usual way.
Note there are a few differences between the xulrunner packages you get from building Iceweasel vs. from building Firefox that need to be addressed, and a few other details to sort out.
