Help with Facebook extension

Hello, I’m having problems with the extension of Facebook, I found a topic here in the community, but this in Spanish and the links that it leaves available is no longer working. CAN SOMEONE HELP ME???

Nobody can help you without seeing that. If you give that link then you are more likely to help.

Here is the link of the video in Spanish, and the links that it leaves are no longer available.
