    Just out of curiosity. The Firefox extension doesn’t seem to get updated as regularly as Chrome, Edge, Opera starting at version 3.18 with Firefox stuck at 3.17.1. Anything to that?

    Reply from Thomas Greiner:

    We’re dedicated to continue to support Firefox, but indeed we weren’t able to bring the latest updates over to Firefox. The problem we encountered is that, unlike other browsers, Firefox requires that extensions offer a way for users to opt-out of any data collection that the extension performs – even non-personal, technical data. So when we introduced basic telemetry to Adblock Plus in version 3.18, we couldn’t get it out to Firefox users.

    Therefore we’re currently exploring different ways on how to best offer such an opt-out to our telemetry to get back on track and deliver new updates for Firefox again.

    In case you’re interested, we’re tracking this issue at, where you should see progress, as soon as everything has been cleared internally.
