Whenever I start or reboot my PC, Firefox automatically opens and displays the Private Browsing window. If I close it and reopen Firefox it then opens at either the previous session or a session restore window. I can't see anything in my start menu that causes this so how can I prevent this happening?

Chosen solution

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 57.0.3 with a Full Version Installer
