Mozilla sent Firefox Version 52.0 to the release channel today. The update includes six (6) Critical, four (4) High, eleven (11) Moderate updates and six (6) low security updates. Firefox ESR was updated to version 45.8.0.

Note in particular the removal of support for Netscape Plugin API (NPAPI) plugins other than Flash. Silverlight, Java, Acrobat and the like are no longer supported. See Why do Java, Silverlight, Adobe Acrobat and other plugins no longer work? for Mozilla's explanation.

I do have portable ESR running on the off chance I want to take XP on the internet but I wasn't sure if the newest version would work.
