FaceBook Auto Liker is a Chrome extension developed by Add-A-Site that allows users to automatically like posts on Facebook. This free extension is categorized under Browsers and falls under the subcategory of Add-ons & Tools.

Once installed and activated, FaceBook Auto Liker refreshes the current tab at a random interval defined by the user and automatically clicks the Like button on posts. If the extension is unregistered, it will only like 5 posts per day.

To access the options page, users can simply hover over the extension's icon, right-click it, and select "Options". From there, users can customize the extension's behavior.

Some of the key features of FaceBook Auto Liker include the ability to run only during specified hours, support for an artificial delay before a click event is triggered after a refresh, and the option to like only certain friend's posts. Additionally, the extension ensures that it won't like a post containing disallowed words and only likes posts with a minimum number of existing likes or reactions.
