Most of us on here for the Help forum are hesitant to click on adware links. So you will to provide a screen of the issue shown on each browser for others to see. Or possible a link to your website so they can see how it is working with the counter.

Hi, thanks for the speedy response. I have attached screen dumps of both sites showing the counter on Chrome but not on Firefox. Thank you

I'd like to reopen this question.

The hit counters on my web site suddenly started blocking the numerical displays for the number of hits. I use amazingcounters.com. On the local folders on my laptop, the hit counters display properly in Firefox, Chrome, and Edge. On the remote sites, Firefox blocks the counters and shows the alt text. Check out allenstown-alt.org. The counter is at lower right. I tried setting Content Blocking to Custom with Trackers and Cookies unchecked. For Cookies and Site Data, I have added www.amazingcounters.com and cc.amazingcounters.com to the Allowed list. Still the hit counters are blocked by Firefox but not by Chrome. What setting is causing this situation?
