Correct, FF 60esr should be entering stable-security more or less within the next hours, so told by by security team yesterday. It would be just a waist of time to create a possibility of co-installation. (BTW: Thunderbird will follow in the next days.) And I never thought about such a possibility in detail simply because the "original" Debian way is to have just one FF ESR package on the system. If users install a separate additional FF package they are on their own, but the system is flexible enough to get this handled. -- Regards Carsten Schoenert
