Hi Cathy and welcome,
I have moved your post to it's own thread to be better able to help you without interrupting that other ongoing thread you had posted in and to bring it in line with our Forum Rules.
We will need more info on your problem....which iPad do you have? What OS is your iPad on....look in Settings - General - About and look for Version. Are you accessing fb through an app or through Safari?
Facebook is huge and makes a lot of demands on ram etc on your iPad and crashes and freezing are more prominent on earlier iPads, most notably on the iPad 1 because of it's smaller amount of ram.
So let us know the answers to the above questions and we will then see what we can advise you to do.
