My last (i hope) error with Debian:

I spent one hour trying to find how in Debian one of the following packaged named mozilla-gtkmozembed|firefox-gtkmozembed|mozilla-firefox-gtkmozembed|xulrunner-gtkmozembed. But ... i can't :-(

What package do i need to install firefox-gtkmozembed?

I try:

# apt-get install firefox-devel
# apt-get install firefox-dev
# apt-get install firefox-gtkmozembed
# apt-get install firefox-gtkmozembed-dev
# apt-get install firefox-gtkmozembed-devel
[download]

But nothing helps me...
