Sorry, the Extended Support Release of Firefox 52 (which you appear to have already) was the last version of Firefox built for Windows XP and Windows Vista.
Firefox 52.9.0esr (Released June 26, 2018) was the last version to still support the old EOL WinXP and Vista as Fx 52 and later Releases has required Windows 7 and later Windows OS's.
Meanwhile Chromium, Chrome and Opera dropped support of the old EOL WinXP and Vista earlier on back in April 2016.
There are still some light 32-bit Linux distros around that you could dual boot with WinXP in order to use current Firefox versions as Mozilla still supports 32-bit Linux Firefox.
