Setting about:config / xpinstall.signatures.required to false fixed extensions for me for firefox 66.0.1-1 amd64 on Debian sid and for Firefox 66.0.2 on Android. I needed to restart Firefox on Debian.
Seems fixed in firefox 66.0.4-1 on Debian sid and firefox 66.0.4 on Android: extensions continue to work after restoring the default about:config xpinstall.signatures.required setting (true).
