Apparently, FGS was banned because one lone game developer made it a point to complain. This particular browser extension was both the least intrusive, and smoothest working, of its' kind. The developer also worked WITH the game developers. so that this extension worked in a way that the game developers agreed to.
The myriad explanations as to "why" this happened can be found in these two articles, at the least, and in the comments to them.
For those who seem to believe that this was anything other than an UNREASONABLE action on the part of Facebook, I suggest that the only way to make REASONABLE would be to enjoin other, BIGGER programs that do what this one did and more. Programs that allow you to do things that one CANNOT do in-game, which is not something this browser extension did.
