The first thing I'm looking for is ad and script extensions. You have two ad blockers I'm not familiar with (2 is a waste, it's extra processing for what is undoubtedly a huge overlap).
There may be settings in either of those that make a difference, blocking trackers.
What is more likely is Firefox's tracker protection settings. Strict will stop embeds, so you will need to set an exception for GAF. You can do this with a dropdown menu on the left end of the URL bar
