I decided I wanted to remove the ipv6 use flag which I have had enabled in

has that use flag and decided I want to know what it actually does. Only, I
cannot find it anywhere in the ebuilds! So where does it come from and what
*exactly* does it do?

I think what the OP is asking, is where the usability of the flags is
specified in the Firefox ebuild(s) - which it quite clearly isn't. If
this is the case, I think the ipv6 USE-flag is added by an inherited
eclass (assuming they can do that) - probably one of the mozilla ones.
