Hi Gabe, it depends. Are you using a button/checkbox on a website to share the content to Facebook, or are you using an add-on? An add-on is more likely to work everywhere, while a website that doesn't have the checkbox visible may simply not be set up for that.

I have a check box appear on some comments, but it isn't there on other comments. I'd prefer an add-on, because at 71, I don't always remember to click the check box. Old-timers', right? (But back home in Newfoundland, Alzheimer's is called CRAFT - Can't Remember A F*cking Thing!)

Hi Gabe, since I avoid Facebook as much as possible, you'll need to get suggestions from someone else on what add-on would be helpful in this case.
