In this Quick Tech how-to video, I'm going to show you how to find liked posts on Facebook from your PC or Mac. From your desktop device… Open the browser of your choice, and go to the Facebook website. Assuming you are logged in, click on the Account button in the upper right-hand corner.
Next, you’ll want to select Settings and Privacy. From this menu, you’ll see a list of options, including Activity Log, which has a little list icon next to it. Click on Activity Log and this will open your Activity Log page.
On the left-hand side of your screen, you’ll see the Activity Log menu. Under Activity Types, you will find the section titled Interactions. Click on interactions and it will open another set of options. In this section, just click on Likes and Reactions to see posts that you have liked or reacted to on Facebook. It’s that easy to find liked posts on Facebook.
