commit a102f8b853fb04db32bcd0f924fd6391cd3d40da Author: Chris Peterson <cpeterson@mozilla.com> Date: Mon Jul 2 11:02:23 2018 -0700 Bug 1472618 - Make navigator.platform return "Win32", even on Win64 OS. r=peterv navigator.platform returns "Win64" in 64-bit Firefox and IE, but "Win32" in 64-bit Chrome and Edge. "Win32" appears to be the de facto platform value for Windows. This change doesn't hide the OS architecture from web content because navigator.userAgent still mentions "Win64; x64" in 64-bit Firefox, Chrome, Edge, and IE.
