I have been using Adblock Plus for many years. Lately, I have become increasingly dissatisfied. Ads were filtering through and the pop-up were driving me crazy. I decided to check the settings and somehow, websites I had not Allowlisted were on my allowlist. I removed them ALL, then I noticed that all the recommended filters were deselected. I thought that strange, but figured perhaps it was a recent update that caused a problem. So, I selected them all. The next day, ads were popping up again, went straight to the filters, yep, everything deselected again. So I selected them all again. I now keep a tab open all the time (moz-extension://11753403-4a29-4257-a10e-ac033906763e/options.html) so that I can re-select the filters every time I open my browser. It is the craziest thing and can't find how to stop Adblock Plus from deselecting my selections!
