9.3 does not show Tag in fvwm, why?

[Jodok Muellers]

Mozilla 9.3 does not show the <title>Tag</title> in fvwm (eg. in FvwmWinList), why?
Name of the first window is just "mozilla-bin" and the following are "Untitled".

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.3+) Gecko/20010910, build 2001091005


How can I make Mozilla showing me the name (title) of the page in my
windowmanager?

Regards,
