I completely removed Firefox and deleted all folders. After installing Firefox fresh, Firefox sees that it was previously installed?? "Looks like you've reinstalled Firefox. Want us to clean it up for a fresh, like-new experience?"

I uninstalled Firefox (supposedly) "completely" using the guide here: https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer

Why does the new install Firefox recognize that it was previously installed? Uninstall tool needs to uninstall Firefox COMPLETELY. Since it lies, can someone help tell me what is the appropriate steps for COMPLETE removal?

Got it going, thanks anyway.
