`platform`	Chrome Yes	Edge 12	Firefox Yes Yes 先前， `platform` would report running on a 32-bit CPU if running the 32-bit version of Firefox on a 64-bit system. This was corrected in Firefox 69. You can override the value returned by `platform` by setting the preference `general.platform.override` to the string you wish to be returned instead.
