Contributing to Firefox

Contribution to Firefox is welcomed. If you need to tweak Firefox in Fedora, commit to master (rawhide) branch only and it's good to ping Martin Stransky <> before any changes there. As Firefox build takes ~ 8 - 10 hours in Koji there isn't usually need unnoticed changes/builds.
