I can confirm this problem. In Thunderbird 69, the customization of the
header toolbar is broken
( And this breaks
my addon Compactheader. So in the moment the only possibility to test
it, is to use the treeherder builds of the comm-esr68 branch
( But the users,
who are on the beta branch of Thunderbird and have downloaded the
lastest version of the addon from ATN will now have a broken version of
the addon.

An again, there is no more beta channel on ATN, so I cannot post a
simple fix for it there.

This is certainly not a good situation.
