So one problem we have with maintaining the post-XUL programs like Thunderbird and Firefox is not only backporting the build toolchain, but also the leaf dependencies.
Enigmail, for example, is broken since Thunderbird 60 landed in stretch: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=909000 Fixing this in stretch will be a significant challenge, let alone in jessie. I wonder how we want to approach this. Presumably, Emilio, while working on Firefox, would also backport the toolchain necessary for Thunderbird, is that correct? Enigmail's work, then, might be better targeted at helping the folks in stretch, although I do wonder how we could possibly upgrade GnuPG 2 (required to get a new version of Enigmail compatible with TB 60) in jessie without causing all sorts of unrelated trouble. Keep in mind that Jessie still runs the old 2.0 release instead of the (recommended) 2.1 (stretch) or 2.2 (buster) releases. So before anyone jumps both feet into patching enigmail for whatever issues are pending there, this should be taken into account.
