FB Post Border от GAMark

This extension highlights Facebook posts that are sponsored and recommended for you.

You know how Facebook integrates ads in the content of your news feed and these ads are so well integrated, that unless you read "Sponsored" or "Recommended for you", you don't even notice.

With this extension you get a color border around those posts that are sponsored and recommended for you.

Red border for sponsored posts.
Green border for recommended posts.
All the other posts are shown as normal.

Note: this is not an "add blocker" like app
