Mozilla has said that it will ban installation of unsigned add-ons in release versions of new browsers, but not in Nightly.
However, when I choose “Install Add-on From File…” in Nightly (43a1), I get “This add-on could not be installed because it has not been verified” error.
But of course this add-on is not verified (nor signed) – this is a new version of my add-on (which is verified and signed), but I work on it locally, and there has to be way for me to install new test version of my extension.
How do I force Nightly to accept test version of my extension?
It says “Firefox will have a setting to disable signature enforcement” – but there is no mention of this setting. Future tense (“will”) might mean that it did not exist – at least yet – at the time of the writing of that article.
If the promised future has already came, then where is this option, how it is activated?
