Hi, Firefox doesn't have a built-in ad blocker, but some of the same scripts might be blocked by the Tracking Protection feature. Firefox displays a shield icon at the left end of the address bar, and it turns a bit purplish then content in the page is blocked, you can click the shield and then click the slider switch at the top of the drop-down panel to turn off Tracking Protection for the current page/site. For more information, see: [[Enhanced Tracking Protection in Firefox for desktop]]. Otherwise, do you have any add-ons that might be blocking content in pages? Extensions such as Adblock Plus, Blur, Disconnect, DuckDuckGo Privacy Essentials, Ghostery, NoScript, Privacy Badger, uBlock Origin or uMatrix 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 improvement?
