For the importance level, this version of Thunderbird is unusable, at least on some systems. Not everyone will find it that easy to downgrade to 38, so it really needs to be withdrawn ASAP before too many people update to it.

I could not send any email, nor spell check. Nothing happened when I pressed the buttons. So I downgraded to 1.38.6.0+build1-0ubuntu1 (and replaced the lightning extension). All now works again. I had to force and lock this version using synaptic. I don't see how this can be anything to do with my setup, since 38 works OK.
