[Bug 1646455] [NEW] Unacceptably slow performance in Thunderbird

[Wolf Rogner]

Public bug reported:

Starting with 16.10 Thunderbirds startup time became agonizingly slow
>From less than 3 seconds (to the blank window) and less than 7 seconds (to accepting input) 
to 17 seconds (blank window) and 28 seconds (to accepting input)
[same machine, same plugins]

Now, with the update to 45.5.1 sending an email increase the time from
pressing send to the disappearance of the window from 1 second to more
than 9 seconds (on average).
