Facebook Post Screenshot is an open-source Firefox extension that you can use. You can install it from the source code because you can install it directly from the Mozilla addons store. After installing you don’t have to do anything, just open Facebook and go to the message that you want to take the screenshot of.

Now, you don’t have to expand the comments or answers because they take care of themselves. Click on the drop-down menu in the corner of the Facebook post and select the “Save Screenshot” option. As you do that, a small pop-up at the top opens and after a few seconds, the screenshot starts downloading automatically. The amount of time it takes to capture the screenshot depends on the number of responses to that message.

You can save the screenshot in an anonymous mode in the same way. You only need to select the “Save anonymous screenshot” option. It does the same in this mode, except that it hides usernames and their profile pictures. This is a useful option if you want to post that screenshot to a number of public websites where you don’t want to show the identity of a user.

This way you can use this simple and useful Firefox add-on to take the screenshot of Facebook. It works with almost all types of messages, regardless of whether they are on a user’s page, group, or timeline. Just one click is all you need to save the screenshot of a message on your PC.
