7 or so years ago? In any case, it has never once let me down, it is the single handed BEST Facebook look and more helper known to mankind. There are a couple others, but they are often complex, detailed, and with all that don't accomplish anywhere near what Social Fixer does. I LOVE, seriously, am IN LOVE WITH the ability to go without any advertising at all, to make my page and layout my preferences, and not Facebook's, and to have all the posts I see going through in the order they were written, and not arbitrarily Facebook's idea of how they should show... Don't use it? You have no idea what you're missing... :) It doesn't affect anything at all publicly, no one else sees your layout. Just you, as you are the one making the choices for your own view of it all. So Facebook isn't affected, nor are random public folks. It is 100% your creation, and shows 100% to you. :)
