Facebook – How to List All Comments Liked

You can check via the Graph API using the ids query.

https://graph.facebook.com/?ids=http://apple.com

{
   "http://apple.com": {
      "id": "http://apple.com",
      "shares": 141119
   }
}

Depending on the website and whether a Like button was available on that page you may get the number of shares instead.

{
   "http://www.imdb.com/title/tt1375666/": {
      "id": "110935752279118",
      "name": "Inception (2010)",
      "picture": "http://profile.ak.fbcdn.net/hprofile-ak-snc4/71156_110935752279118_1973266_s.jpg",
      "link": "http://www.imdb.com/title/tt1375666/",
      "category": "Movie",
      "website": "http://www.imdb.com/title/tt1375666/",
      "description": "Directed by Christopher Nolan. With Leonardo DiCaprio, Joseph Gordon-Levitt, Ellen Page, Ken Watanabe.",
      "likes": 46015
   }
}

You can get this info using the Graph API. One way to do this is to go to the Graph API info page - http://developers.facebook.com/docs/reference/api/

Here you will see links to get information about yourself (Profile details, Likes, Photo Albums...). These links contain an access token which is only valid for a short time so you cannot bookmark these links.
