Thanks Michael, I already found that. You may find there the
relationship between XPCOM C++ bindings for Gecko and how to use them
in fpc app. In my case i'm interested to access the adressbook in
Thunderbird. Even if I would get along to find the right functions I
have no idea how to process returned data. I guess you have to be a
very good C++ developer for that as well. But that's ways over my
skills, I think.

Thanks for your help.
