I've installed the first one you listed, but it's not blocking the ads on one of the websites I frequently go to. And yes, I did restart Firefox and it's still not getting rid of the ads.

What ad? It might be part of the web page.

The ads on the website. The website I'm talking about is fanfiction.net The Adblock Plus add-on isn't blocking any of the ads.

I went to that link but saw no ads. Were they on a different page?

I just went to the website & it's still showing ads for me.

Here's a screenshot of what I'm seeing. The ad in the shot is one of those moving ads (a gif-type ad).

Hi  !
Your screenshot shows that the   Adblocker  icon is greyed out,   which means that you've got to click on it and activate it.

I didn't even notice that! Now it's working. Thanks.

If you find a site where you do not want the ads blocked; Load the web page. After the page is loaded, click the down arrow next to the AdBlock icon. Now select Disable on <website>. Reload the page.
