# parabola changes and rationale
# FSDG:
#  - Modify the addons pages to use GNU IceCat plugins sources, rather
#    than addons.mozilla.org, which hosts non-free addons
#  - Disable EME, which is implemented via the non-free libWideVine CDM
#  - Disable Normandy that let Mozilla push messages with recommendations
#    of nonfree software
#  - Make Remote Settings work completely offline using local data
#  - Rebrand to Iceweasel, per the mozilla trademark policy,
#    due to these FSDG changes
#
# technical:
#  - build i686 with GCC instead of clang
#  - disable rust-SIMD, LTO, PGO, and skip profiling build for armv7h and i686
#  - allow skipping profiling build for x86_64 (_x86_64_skip_pgo)
#  - prefer as many system libs as possible, over their vendored couterparts
# 
# privacy:
#  - Remove Google API keys and usage
#  - Disable Mozilla telemetry and crash reporting (good manners
#    because of all of the other patching we're doing)
