There was news about a chrome extension for the same tool recently floating around. But during our speculation, we couldn't find the exact link for the same. Therefore, either the extension isn't valid anymore or is down for maintenance. We will update about the same as soon we find out more about it This software is amazing! I used to take hours when I wanted to reduce my friends list, going through one friend at a time. BUT I didnt know who was engaging more than others. Friend filter helps you find true friends who like, post and share your posts. And its also as a result improved my reach. Hret software This Facebook Friends Mapper extension for Chrome will Help You.
