If it doesn't solved your problem, then feel free to ask in Reply Section. Thanks for raising your question in Mozilla Suport Forum.

HI supermexbg, here's one other thing to check:

Could this be due to the Enhanced Tracking Protection feature? You and your readers can manage what that feature blocks in pages using the shield icon at the left end of the address bar.
