GMail has made their site just a little safer. They've changed the site address from http to https. This helps to encrypt your messages as they go from your browser to the server. Of course, with the good there is always the bad. This will slow down your computer while you send messages. This is why Google gives you the option to turn this feature off. Of course now https is the default for it so you can just go to settings and turn it off if you wish.
