How do I unlike external pages on Facebook?

[Marian]

Beneath or beside the external website or page, you will see 'like' or 'unlike' click it but this depends on ur previous actions. That is,if you previously liked a page or external website,what you will see is 'unlike',then to unlike it,click on the 'unlike' and vice visa . But if the website or page was liked by your friend through her own page,there is nothing you can do about it,except if he or she gave u access to operate through her page. A website or external document that has been 'liked' by someone can only be 'unliked' by that same person using the same page he/she used earlier or by someone given permission to use that same page. You can't carry out an action for another person usikg your own page.
