I looked in the Thunderbird preferences and under Automatically check 
for updates, Thunderbird is checked but it is greyed out. When ever 
Ubuntu's Update Manager has notified me of updates I have given it 
permission to perform the updates.

Or is there somewhere else I should be looking?

Thanks,  Jim
