I'm not sure if this is purely a Firefox issue or if KDE is involved. When saving from Firefox the save dialog window looks like it is KDE and it remembers some KDE settings. The detailed tree list view for one thing.

However, the icon magnifier is always too large. I keep setting it back down, but on the next Firefox save the icons are huge again. I would really like to change this really annoying save dialog window default icon size. Anyone have any idea how to permanently shrink these icons, or is this an issue that belongs completely and only to Firefox?
