windows 10 64bit, latest firefox install. i see an issue with my keyboard typing the wrong characters in firefox, it seems to randomly replace the character i press on the keyboard with a different one. I can be typing something into a webpage, either ebay or facebook, or even an address on any ecomerce site, and i get ridiculous spelling issues. E.g i type "firefox issue" into this page, and i get "firefix issue" if i goto the the "O" btton on the keyboard, and hold it down, i get "iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiioiiiiiiiiiiiiioiiiiiiiiiiiiiiiiooiiiiiiii" or some other random pattern. I don't have any emoji extensions installed, and have zone alarm installed, and its up to date too. Any ideas??
