A few months ago I installed AdBlock for Firefox, and it has been working great. However, a few good websites give a message asking that I remove my ad blocker, and I would like to disable it for those sites. Problem: How do I find this app/extension on my Mac? I've done all kind of searches but am unable to locate it. Or maybe there is something else I should be doing? I've searched my Firefox 44.0.2 Preferences and don't see anything there. I've also checked the AdBlock.com site but found nothing there. Thanks for any help!
