Running adblock plus on firefox completely ineffective

I just recently purchased a Macbook pro and have downloaded firefox as my web browser. I installed the add-on adblock pro, and it is without a doubt 100% ineffective; I view web pages and when I place the mouse on top of the icon it tells me it is active, however below it notifies me that it has blocked 0 out of 150 or however blockable items on the given page. I mean absolutely nothing is prevented, I found a similar add on for safari, and the same results, nothing blocked. I must be doing something completely wrong, or something so blatantly obvious, but I really am clueless.
Does anyone have any suggestions?

 

No I have no subscriptions, I don't know what could interfere with those functions, something seems inherently wrong. I literally just bought the computer yesterday.

 

I'm not given any option to choose a subscription when downloading, I just click ok and then it asks me to restart firefox after it's installed.

I found that easy list subscription online and now I am seeing results, and yes I understand the logic that there must be a list out there, I just assumed that abp would already carry it. Bad assumption,
thanks guys and gals
