Hi Gregh,

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
