On an XP system (as of last night), FF told me that version 51.0.1 was up-to-date. I was not offered v52, nor was there any indication that I would/should be migrated to the ESR version. Just wondering what other XP+FF users have experienced.
(Note: I am not looking to have this post diverge into a discussion of the merits/dangers of still using XP. Just trying to find out whether/when FF on XP might be automatically migrated to ESR, or whether that's something that one needs to perform manually.)
