[Pkg-mozext-maintainers] Bug#913445: Broken with Thunderbird 60

[Moritz Muehlenhoff]

Source: imap-acl-extension
Severity: grave

When installing the plugin on Thunderbird 60, it's disabled and only prints
"IMAP-ACL-Extension is incompatible with Thunderbird 60.3" on stretch and sid.

TB 60 was uploaded to stretch two months ago (and three months ago to sid), given
that noone filed a bug so far, it makes me wonder whether this package is used
at all...

Cheers,
        Moritz
