Hello!

Thanks for reaching out to us. No, you do not have to pay to use Adblock Plus. If you are seeing ads, its something we are more than happy to troubleshoot with you via support@adblockplus.org. Acceptable ads can be disabled in settings, but please note that the ads you are seeing are likely not acceptable ads. If you are having issues with seeing more ads and reporting them feel free to reach us at the email above we are happy to help!

Thanks
Shannon
