Try downloading from www.mozilla.org/firefox/all/ and reinstalling.

Firefox 62.0 does require Windows 7, 8, 10 to run.

Hmm well then your only option is to use the now End Of Life Firefox 52.9.0 ESR (32-bit).

Otherwise you need Windows 7 or later or consider dual booting with a light 32-bit Linux distro like Lubuntu or Xubuntu or some other light Linux options. Not as many still support the ancient 32-bit CPU's now days though as most support the 64-bit CPU's from AMD and Intel.
