The Pros: It is always a good idea to view things on a Secure Server whenever possible. Essentially what this option does is add a layer of encryption so that someone can't theoretically break in or "hack" your computer while you are viewing things. Typically, whenever you are dealing with something like a Bank Account or buying something on a Shopping Cart, it is essential to make sure that you are on a secure server. Always look to make sure that it says "https://" and that the little lock symbol on your browser is showing that things are secure. So, it's a nice idea to consider that FaceBook should be secure considering all the information you are putting into your account and the amount of viruses that seem to prop up on FaceBook.
The Cons: The real problem with making FaceBook work on a Secure Server is that not all the information on a FaceBook page is secure in itself. So, if you choose this option you will likely get constant pop-ups warning you that "...some items on this page aren't secure..." or you'll get prompted by the browser regularly to allow this sort of thing to go through. By allowing it, you are automatically breaking part of the security, but if you don't then you can't view it all. Realistically, most of the information on FaceBook is pulled from somewhere else. Pictures and videos especially come from other website links, so these automatically aren't secure. Thus, it becomes a real pain to deal with it if you choose this option.
In conclusion, you have to choose how secure you want FaceBook to be for you. Most of it is already so open to the public that in our view it's part of the point to leave it open. It is after all - Social Media. But, if you are very security conscious, then you would want to do this. You have to decide for yourself if it is an issue and what you are willing to deal with to have that layer of security.
