Attention #Fennec #FDroid / #Firefox users: The critical 66.0.4 update is now available via F-Droid to fix the broken add-on support because of an expired certificate. That was incredibly fast for F-Droid standards! Don't forget to revert any unofficial fixes. https://f-droid.org/app/org.mozilla.fennec_fdroid
@CryptGoat Installing https://storage.googleapis.com/moz-fx-normandy-prod-addons/extensions/hotfix-update-xpi-intermediate%40mozilla.com-1.0.2-signed.xpi manually (if you have Normandy disabled or it's not triggering for some reason) is a better hotfix than that anyway.
