I have Windows 11 installed on my computer, but when I open Firefox (or sign in) it appears that Firefox thinks I'm running Windows 10! Why is this happening, as I no longer use Windows 10.

If I have Windows 10 files on my laptop: do I need to DELETE all these in order to use Windows 11 functions with Firefox?

To answer the question.

A Firefox 151.0.2 UserAgent or UA on Windows 10 and 11 displays as Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:151.0) Gecko/20100101 Firefox/151.0

Windows 11 is basically based on the same NT 10.0 as Windows 10 which is why some sites may think you are on Windows 10. Perhaps when Microsoft actually makes a new version of Windows it will be based on a new NT. https://en.wikipedia.org/wiki/Windows_NT#Releases
