I use AddToAny and due to the nature of it being a 3rd party script for social media, Firefox blocks it by default with their Content Blocking policy. To disable it, watch the 14-second video below.
If you still can't see it after doing this, send me an email.
In the future, I plan to investigate this further and look into ways where you won't have to do anything and it would "just work". But for now, this is a temporary fix I found. Sorry for the inconvenience!
