Mozilla is excellent at maintaining an archive of all their past releases. You need to navigate to their FTP server.
Once inside the 52.9.0 folder, you will see a list of languages (e.g., en-US , en-GB , fr , de ).
Do trust random "Firefox for XP" download sites. Many are filled with malware or adware. Get the file directly from Mozilla’s official archive server.
If you absolutely need daily secure browsing, consider dual-booting a lightweight Linux distribution (like Puppy Linux or Zorin OS Lite) on that same old hardware.
