Firefox Flash Games Scroll is Reversed

for some reason when using Firefox any facebook game i play that uses flash the scroll is reversed. so if you scroll up it zooms out in the game and if you scroll out it zooms in in the game. this makes no sense. it  was working but now its not. i have done clean installs, uninstalls reinstalls. i have the latest flash, latest firefox, windows 10 1709 64bit. all my browsers are 64bit as well. any suggestions? this is highly annoying. i also am on a fresh install of windows done this morning.
