This app requires interaction with other friends contact info. I have tried many times using Firefox where Norton Safe Web and identity Safe are on duty, to play words with friends. After several help desk resets, it still doesn't work for interacting with other friends. Games from the same company work just fine as long as they don't have to interact with other friends. The game works great using google chrome where there is no Norton. Any one know how to resolve this with firefox? Is Norton the issue? firefox? Facebook? Zynga? thx
