Likey is a free Chrome add-on developed by freginold that allows users to quickly see which Facebook posts they have liked, which ones they haven't, and which ones are ads. With just a click of the Likey button, users can easily differentiate between liked posts (colored blue), unliked posts (colored orange), and sponsored posts (colored red).

One of the key features of Likey is its automatic coloring functionality. As users scroll down their Facebook feed or view a friend's posts, Likey will automatically color the posts in blue, orange, or red, depending on their like status. This makes it convenient for users to identify their liked posts and keep track of their interactions on Facebook.

It's worth noting that currently, sponsored posts that have been liked by one of the user's friends appear in orange, but this will be addressed in a future version. Additionally, if users refresh the page or navigate to another Facebook page, they will need to click the Likey button again to run the add-on on that page.

Likey encourages users to report any bugs they encounter by leaving detailed comments, ensuring that issues can be addressed promptly. The developer also welcomes suggestions for further improvements to the add-on.

Overall, Likey is a useful tool for Facebook users who want a simple and efficient way to keep track of their liked posts and easily identify sponsored content.
