An excellent question.  Currently I run Thunderbird on both Linux and
Windows, and right now it's Windows that is giving me the "update NOW"
messages.  I almost never use the Linux version, preferring to
remote-desktop into my Windows-based work machine, because at least then
I have a chance of making sure my Mozilla-provided Lightning calendar
extension will actually work.

As for the Linux version, I honestly don't know.  Perhaps a separate
utility to scan the XPIs installed and check the Mozilla database
against the new version?  I don't know if that's possible, or even if
that's a realistic thing to suggest.  I am not a programmer, or I would
try doing something like that myself.
