Hi all, I am not sure whether one of you has more information about an incompatility of the "JS Print Setup Addon" with the new Firefox version 57 going to be released on 2017-11-14. It seems that the new Webextensions API used with Firefox 57 does not provide the functionality required to build a compatible version of the "JS Print Setup Addon". See https://github.com/edabg/jsprintsetup/issues/39 and https://bugzilla.mozilla.org/show_bug.cgi?id=1385827 With an activated automated Firefox update function the update is going to be installed automatically after 2017-11-17 which makes the silent print feature likely to be dysfunctional. Looks like blocking the FF 57 update until the issue is fixed is the only way for now to keep the silent printing feature.
