Hi there,
Thank you for your feedback! We should still be working with the version 66.0.3.
However in the past 24 hours there was an issue with an expired certificate in Firefox, causing ALL add-ons to be turned off.
Firefox has now pushed a fix for this, which should be installed automatically for you. You can find more information on it here: https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/

If this issue still exists past Sunday, please reach out to us via support@adblockplus.org!
Thanks,
Jessy
