Thank you for your feedback and for sharing your insight! However Firefox is actually experiencing a certification issue which is causing all these issues with add-ons. They've pushed a fix which should arrive in the next couple of hours: https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/
If you're still having problems past Sunday, please reach out to us via support@adblockplus.org! Thanks, Jessy ABP Support Team
