Hi MB,

Installing NoScript will offer a lot of protection. However, FaceBook is very much the lion's den. I'd argue that you can't be safe and use Facebook, but I think it's a risk the vast vast majority of people are happy to take. Best advice I can give is to be ever vigilant, be suspicious of anything that ever asks for any important information, no matter who it appears to come from, and never ever install anything sent to you over FaceBook.

Bart.
