Hi cpharris22, Firefox doesn't have a built-in ad blocker, but the Tracking Protection feature can block tracking scripts and sites may assume it was blocked by an ad blocker. The shield icon toward the left end of the address bar usually turns a bit purplish when content is blocked. Click the icon to learn more or make an exception. See: [[Enhanced Tracking Protection in Firefox for desktop]]. Also, do you have any add-ons that can block content? These include Adblock Plus, Blur, Disconnect, DuckDuckGo Privacy Essentials, Ghostery, NoScript, Privacy Badger, uBlock Origin and uMatrix. These usually provide a toolbar button to manage blocked content in a page. There may or may not be a number on the icon indicating the number of blocked items; you sometimes need to click the button to see what's going on and test whether you need to make an exception for this site. Any progress so far?
