Stuck on the loading login button

Hi team,

I have a quick question. I use the plugin for a website and the plugin itself is great. However, sometimes there is a strange bug:

When I try to log in with my facebook account the loading button is stuck and it is not logging me in. It just keeps loading and loading. (You know when you click the button it starts to load).

I reproduced the bug only in Firefox. When you turn on your Firefox tracking protection it blocks the facebook sdk file and nothing happens. The button is only loading.

However, I received some queries that this happens and on android devices using Google Chrome. Of course, I tried it there too and worked perfectly.

So I am not sure what might cause this issue. If you have any idea I would really appreciate it.

Best,
Ivan
