- 3np 2y agoAs of recentlyish, I noticed this is not an option on ESR, either. Only Nightly and Dev. https://wiki.mozilla.org/Add-ons/Extension_Signing#FAQ https://wiki.mozilla.org/Add-ons/Extension_Signing#FAQ The FAQ says that in ESR, xpinstall.signatures.required should be respected but this is out of date IME (ESR 115).
