Kent, I've said this before, and I'll say it again: The Thunderbird
project stands no chance at all to maintain security patches of Gecko.
There is a reason why Mozilla provides the ESR only for 8 months:
Because it gets increasingly difficult as the branch and mainline
diverge. At Mozilla's security does not have the resources to maintain
the branch longer. There are security bugs every 2 business days! Some
of them are easy, some complicated, some very very hard to fix on the
If the Mozilla security team can't manage, why do you think the
Thunderbird project can?
On top of that, our TB maintainers even lack the security knowledge to
understand Thunderbird's security model. Gecko security is 20 times
harder. There's absolutely no chance we can get this right. We might be
able to manage in 9 out of 10 cases, but what do we do with the rest?
With 2-3 security bugs per week, we'll be flooded.
Kent, please stop proposing that as option. It is not. Nobody has
managed to do that. Ever. Not Redhat, not Debian, not even Mozilla. And
I have inside information about some commercial projects that I am not
allowed to share, who are in much worse situations. Not just 1, but
several. They all made the same mistake. They all started like this
here. Please take my first hand experience and learn from it. Please
don't repeat that mistake here.
This is not feasible. If we depart ESR, we have a few months at best
