Service workers and push notifications are disabled on Firefox 52 ESR

Published: | Categories: DOM


The Service Worker API and Push API will be disabled on Firefox 52 Extended Support Release (ESR), as with Firefox 45 ESR, due to the upcoming major architectural changes to support multiple content processes in the browser. Firefox 52 ESR is mainly for enterprise users as well as Windows XP/Vista users who cannot upgrade to Firefox 53 and later. Those APIs are available for regular Release channel users.

Update: Those APIs are still disabled in Firefox 60 ESR.
