Well I got a Norton automatic update to 360 and version 2 has really messed up my FireFox browser. The URL histories are jumbled and the keystroke fill ins aren't working now. Used to be I would type in the boxes just a few letters at most and firefox would remember and fill in the rest. More often visited sites would stay near the top of the url history list but not now.
I've uninstalled Norton and now I'm going to uninstall/reinstall FireFox.
