each time I download something ie from firefox such as facebook video calling it will not open I have to go to the downloads folder in the finder and then if I click on it it says can't open because it is from an unknow developer.... this happens wih all downloads. How can I change this??????? PLEASE HELP with basic instructions thanks (I get confused with the tech jargon).
