How to disable the ad blocker of Firefox?

[csaba]

That pop up thing that shows up on every page is bloody annoying. I tried googling how to disable the ad blocker but the answers don't help. I don't see shipspotting anywhere, or any other website that is on my favourites list.
Help as step by step instruction is very welcome.
Thanks

Should be able to "pause on this site" but appears it only affects the open tab. Being as SS opens a new tab or page every time you click on something the above "pause" has to be done again and again!! Something else that needs to be looked at.
