I use kwrite as well for quick and dirty editing of simple text files. :) I have the *.txt mimetype associated with kwrite. I have all programming language mimetypes associated with kate.

Firefox is unique in that the user has to specify the external editor to use. There is no mimetype association per se like the files opened through konqueror. Changing that external editor in Firefox to kwrite will open the web page in kwrite rather than kate. For me that would result in the result in the same behavior: two editors open in two different windows. :)
