Strict your Privacy with facebook unseen-

Facebook recently introduced a new privacy feature from which your friends will get to know when you have seen the last message they sent.
This might be pretty annoying in the situation, you really don't want to chat with someone or want to avoid him/her.
Now i will tell you about a cool chrome extension named as "facebook unseen".
This extension stop the specific script from executing which let Facebook detect whether user have clicked on chatbox or seen the last message or not.

This extension can be downloaded and installed straight from the Chrome web-store-
