When we visit our site visitcedarhilltx.com on Firefox we get blocked with a message that says "Blocked by Content Security Policy." What is this and how can we remove it? Doesn't show up in other browsers.

hello PatriciaMB, your site consists of an iframe wanting to show contents from cedarhilltx.com - however that domain specifies with a content security policy that it may not be displayed in a frame on other domains & firefox is acting on that. you'd need to get in contact with the webmaster of the page to get that policy removed or appended to include your domain.
