I've uploaded for jessie-security and
for stretch-security, thanks!  They're also available on the "jessie"
and "stretch" branches at

I'm less concerned with "all these extensions" than i am with enigmail,
which i think is an important one, until we manage to get it embedded in
thunderbird directly :/ I understand that the release team has a larger
scope, but dropping enigmail from debian stable would be a pretty bad

i'm not sure which release time you're talking about.  

Thunderbird 52 has not been part of any release, afaict.  i think it was
pulled into jessie and stretch by way of security updates.

We have known that thunderbird 52 is incompatible with prior versions of
enigmail from earlier this year (~2 months ago, see the upstream bug
report).  We just failed to coordinate it properly for the security
update of thunderbird in debian stable and oldstable.  Sorry about that!

At any rate, i think it's working now (modulo a follow up on Paul van
der Vlis's experience of sending out cleartext mail as a separate
issue, which i'm unable to reproduce).  Please follow up if the updated
packages haven't resolved your issues, Shevek.
