navigator.platform now returns Win32 even on 64-bit Firefox

Published: | Categories: DOM, HTML

Description

Starting with Firefox 63, the navigator.platform property will return "Win32" on all Windows platforms, even on the 64-bit version of Firefox. This change has been made to avoid potential web compatibility issues, given that both 64-bit Google Chrome and 64-bit Microsoft Edge are returning "Win32" on purpose. Meanwhile, navigator.oscpu and navigator.userAgent will continue revealing the real platform.
