Firefox print to PDF

Why doesn't Firefox have a export as PDF function yet? This is one of the features I use most in OpenOffice. When I need to do it from Firefox on Ubuntu I need to print to Default/Postscript, and save to file, then use ps2pdf from the shell to convert it. However, it just just be a click away!

From KDE System Settings, I can add a new Printer as GENERIC->Postscript Printer but that file is still a PostScript file and not a PDF! The pseudo printer is a simple idea, with PDFCreator and CutePDF being available which acomplish it this way. Will Firefox 3 have this missing feature?
