FireFox configure problem

[Andrew Muhametshin]

I have ports iconv and libiconv instaled.
But at installation from ports, all pograms based on 
mozilla(thunderbird, firefox), does not find iconv and on this not 
correctly save files in which names there are not latin symbols(In my 
case - Russian symbols).
