Re: What is the latest version of Firefox ESR that will support Java Plugin? What date will it be scheduled to run until?
A version on ESR channel tends to get eight major updates so 52.8.0 ESR may be the last.
However this time there will be at least two reasons for regular Firefox users to use 52.0 ESR. For to use Plugins and for Windows XP/Vista users to still get security updates as Firefox 53.0 and later will require Windows 7 or later then.
Firefox 45 ESR is currently at 45.6.0 esr because 45.6.0esr came out when Firefox 50.1.0 was Released as otherwise 45.6.0esr would have instead came out when 51.0 was Released.
