Can't access ftp site using Firefox/SuSE 9.3, but can access the site using Konqueror/SuSE 9.3.

Hi, everyone. I am not able to access an ftp site using Firefox and SuSE 9.3, but I am able to access the site using Konqueror. When I use Firefox (verson 1.0.7) I get an error box that says: 530 Sorry, no ANONYMOUS access allowed. And I am not presented with the box for inputting the password and username. When I try using Konqueror (version 3.4.0) I am presented with the box for inputting the password and username. Upon insertion I am taken to the ftp site -- no problems. Any ideas on how I can get Firefox to allow me access to the password/user box and, thus, to the ftp site? Thanks! Gil
