Don't ovewrite system files Firefox critical Windows OS?

I work in a school district. We use software to information student Tyler. I have Firefox and IE 10 on our computers. Tyler works but sometimes it does not update the alignments of the student. We were using IE then found that Firefox worked better. We still have random problems with Tyler. Our superiors contacted Tyler and they told us that it is not their problem, but a problem of Firefox. They said Firefox crushes the critical system files and we have now for reimage all our computers. Is it true that Firefox can overwrite some system files is critical?

Thanks for the update; I hope that other users of Tyler will find it in the search the Web and benefit from your research.
