New to Keep and Keepbird

I use Thunderbird to collect mail from 3 sources. Thus I need 3 different passwords. Futhermore 2 extensions need a user name and or a password. How would I be able to manage that with Keepass and Keepbird?

Whats the problem to use pure KeePass with Auto-type to fill out the password questions.
There is nothing special on such password questions of non-browser based applications.
Its one of the best KeePass features that you can fill passwords in any application.

I was just wondering if it is possible. And your answer show it is. Thanks.
