At long last the timetable is capped off with the discharge channel for the more extensive public.

A 64-bit Firefox for Mac OS X and Linux has been accessible for quite a long time, however on Windows the gimmick never made it past the Nightly channel. In November 2012, Mozilla quietly killed off 64-bit Firefox, just to invert the choice after a month after gigantic kickback from clients.
