Comment 125 for bug 233901

http://www.mozilla.org/catalog/end-user/customizing/briefprefs.html says
"feedback and comments here", so here is mine

I can't find out what fcc_folder_picker_mode means. I've come across it in my
thunderbird installation, while trying to debug something else. But I don't
know what it means, and there does not seem to be a cannonical reference to all
these preferences anywhere in the documenation.

I'd like to see a full, maintained, list of what they all are and mean. Does
anyone know where it is?
