I had to upgrade my Firefox for Mac and it took forever, I have an old version and wonder if or how to delete it? When I open Firefox I get a warning saying it may not be safe due to a download from the internet?

I have Firefox 4.0 for Mac, and it couldn't update. I downloaded 8.? and wonder if I should remove the other 4.0 that is on my desktop? Not sure if I should or how? When I open Firefox it warns me that it could be unsafe as it was downloaded from in the Internet?
