Facebook is an interesting phenomenon whereas its users are not the customer, they are the product. What this means is they collect information about you and then sell that information to whoever wants to buy it. When it comes to their platform, I understand the information I post there will be sold as such. What I don’t agree with is the fact that they are keeping track of me in other places on the web that have nothing to do with Facebook; places that have to do with my employment and finances.
Imagine my surprise when I went to my trade union web site to discover that one of the scripts it was trying to run was from facebook.net. Equally as disturbing was when I went to my online banking site with my credit union, the same script from facebook.net was also trying to run. This script was trying to run even after I logged into my sessions at these respective sites. I tagged this script as “Untrusted” at these sites, so it cannot run. These web sites continue to work perfectly fine without the script from facebook.net.
As far as I’m concerned, NoScript is a valuable add-on for anyone who wishes to browse the Internet under their own terms. Not only will it protect you from malicious scripts (assuming you don’t mark a malicious script as “Trusted,”) it also puts giant marketing creeps back in their place while I do my personal business free from their prying eyes.
