EXCERPT: Mozilla Firefox 52.0 Stable was released on March 7, 2017 to the public through the web browser's automatic update functionality, and on Mozilla's website. [...] The new version of Firefox is a major release for several reasons. First, it is the first release that does away with NPAPI plugin support. Second, it marks the beginning of a new Firefox Extended Support Release (ESR) cycle.
Mozilla updates all Firefox channels on the same day when a new major stable version is released. This means that Firefox Beta is updated to Beta 53.0, Firefox Aurora to Aurora 54.0, and Firefox Nightly to Nightly 55.0. Additionally, Firefox ESR 52.0 is available (and so is Firefox ESR 45.8).
Executive Summary
(1) Firefox 52.0 is the new stable version of the web browser.
(2) The new version does not support NPAPI plugins anymore, apart from Adobe Flash. So, no Silverlight, Java, Google Hangouts and other plugin support anymore.
(3) Firefox ESR 52.0 is the new Extended Support Release version. You may enable NPAPI plugin support in it.
(4) Windows XP and Vista users are automatically migrated to Firefox 52.0 ESR during update. Firefox 53.0 won't run on XP or Vista machines anymore.
