Hello, I inadvertently used the option Block Element to get rid of a horrible recurring spam post on FB. I thought I was just blocking that post but what it ended up blocking the options on my whole Facebook program, so now I can't edit/undo anything on my FB page. I know it's within Firefox as it doesn't happen on the other browsers when I am using FB. I tried to look it up but can't find anything to help me. I was hoping I could end up talking to a real person as I know it can get confusing but perhaps you can give me step by step instructions? I need to know how to UNDO blocking an element. I've attached an image but I'm not sure if it fully explains what I'm dealing with. Thanks, Ellen Claxton
