iframe not displaying content. (I own the webpage I'm trying to display)

[Nirmala]

My iframe banner ad displays on Chrome and Edge browsers, but there is just blank space on Mozilla Firefox.

Here is my site: www.freespiritualebooks.com and the banner ads are from Amazon

Any ideas on how to get them to show up on Firefox?

Oops. I had my ad-blocker turned on for my own website.

Iframes are working fine now.
