A window opened saying it was a Firefox security scan and opened a window to download FirefoxPatch.exe which supposedly fixed a problem. Is this legit or do I have a problem if I run it. How would I recover?

It is 100% FAKE

If you downloaded this .exe and yet to install it, do not install it as it can install the nasty CryptoLocker trojan which can lock files on Windows and is hard to remove.

Firefox updates are done internally in Firefox (by way of a .mar file) and by download from www.mozilla.org and www.mozilla.org/firefox/all and Mozilla does not host updates outside of *.mozilla.org sites.

There are no .exe patch updates since Firefox is not just for Windows but also Mac OSX and Linux.

This fake patch scam has been around for a couple months now and it popups on some sites is preying on inexperienced Firefox and or Windows users to get them to install a trojan.
