However a dataloss bug was uncovered, where "Detaching attachments corrupts the main body of the e-mail text" - probably not something most users do but regardless an undesirable result.  Therefore updates to 52.9.0 have been stopped and the version removed from official Thunderbird download pages.
Downgrading to 52.8 causes Lightning to be disabled. Thunderbird offers to search for a compatible version, but does not find one. Lightning was embedded precisely because of its version dependence, but that apparently does not help in case of downgrades. Maybe it should.

And readers of tb-enterprise should be informed.
