I am running Ubuntu Linux with a Firefox browser.  When I try to start
Webhttrack nothing happens.  I have a feeling webhttrack can't find Firefox
but I'm not sure.  When I type httrack in a terminal the program starts but it
won't allow me to input a previous project name.

I have looked around for a configuration file but all I seem to have are the
executables for webhttrack and httrack.  Can someone give me a hint as to hat
I should do next?  Thanks.
