How to tell Safari/Firefox to always use the expanded Print Dialog?

Mac Os X has 2 forms for the Print dialog - one collapsed and one expanded. Is there a command that would set Safari and Firefox to always use the expanded print dialog? Everywhere I searched I came to the same answer that doesn't work:

defaults write -g PMPrintingExpandedStateForPrint -bool TRUE

I tried that setting, verified that was successfully written in the preferences files but I still get the collapsed printing-dialog on Firefox and Safari. Is there a way to setup things so that Safari and Firefox never show the collapsed Print dialog? Thank you

defaults write -g writes to the global preferences domain, over which the application domains take precedence. If you want this to work in Safari or Firefox, then use their preferences domains instead, e.g. defaults write com.apple.Safari PMPrintingExpandedStateForPrint -bool TRUE.
