Firefox Browsers have an issue traversing through directories in certain FTP sites,
if you are experiencing a problem please try one of the following :


Append a slash "/" at the end of the URL your are attempting to access, for example : ftp://ftp.delta.dfg.ca.gov/salvage/

If the above solution does not work 

	(a)  either use Internet Explorer (IE) or 
        (b)  Download a FTP plug-in for Firefox, at : 
             https://addons.mozilla.org/extensions/moreinfo.php?id=684
             
             Such as : FireFTP  https://addons.mozilla.org/firefox/684/
