Bug Description
Binary package hint: xulrunner-1.9.1
The xulrunner stub used to build firefox is still non-relocatable, so a portion of the firefox memory image is predictable. As part of the security team workitems, firefox should be built PIE. There are no performance regressions, as tested by a javascript performance tool:

First two are stock firefox, second two are PIE firefox.
Attaching branches that implement PIE via hardening-wrapper. I attempted to use hardening-includes, but something in the build does not correctly respect CFLAGS, CXXFLAGS, or LDFLAGS defined in the debian/rules file.
