Bug 806068's patches just landed, adding support for the unprefixed CSS keyword "initial", and retaining "-moz-initial" as an alias. Filing this bug on removing support for "-moz-initial".
There are still six references to -moz-initial in comm-central...
Thanks for the heads-up -- I filed bug 807303 on fixing those. Maybe you'd like to take it? :)
