I've been playing zynga farmville 2 for a while now never had any issues, that is until the other week when the new avast 2014 fire-fox web security plug-in got installed. It blocked all my gift requests from other face book users, also some graphics, it also disabled me from posting any of my requests in the game, I thought it was a browser issue and for the last week i have been scratching my head and puzzled as to why it was happening thinking it was either zynga or the latest Mozilla update. Finally I read in a help forum that disabling the avast web plug-in would solve the issue and it did. Facebook games are not viruses, nor I am impressed that your plug-in blocked so much facebook content. Its one thing to protect against viruses and spam, its another to mess up functionality in harmless face book flash games, your meant to be number one anti virus program, I didn't expect this. Just thought I would make other users aware of this serious issue and avast programmers please sort asap. Thanks.
