hi omole, adblock is an extra addon that users would have to separately download to use in the first place. it isn't present in your configuration as it seems. perhaps the firefox tracking protection is interfering with the advertising networks that are used on that page. you could for a shield symbol on the top left of your firefox address bar where you could disable that protection momentarily for the site: What happened to Tracking Protection?

I have the same problem. There are some sites I want to use that won't display unless they can place ads which is fine with me. But Firefox won't allow them. It's no good saying to disable the shield on the top left of the address bar as there is now shield. I am having to use Chrome to get the sites I want. This is a bit of overkill on Mozilla's part.

The above post should read "no shield symbol" not "now shield".
