Mozilla Firefox compatible with Windows XP

There are machines within the company that only run on Windows XP. It is impossible to redo the system because of the applications it contains.

I tried Google Chrome, Opera, and a version of Firefox, but nothing works. That's why I need a version of Firefox compatible with Windows XP.

These machines are used for business applications, right? Are they physical or virtual?

In any case, I advise against giving internet access to your machines running XP; I think you know why.

Sure,
