mozilla-1.1 is in Debian unstable. I run Debian testing into which packages
from unstable migrate after two weeks -- unless there are unmet
dependencies or bugs or ... With something like gnome or mozilla the
migration is often delayed.
But if the feature is missing in 1.1, I am not sure I can do something
useful here. Too bad.
