I think it's a function of the endless tussle between browser-as-an-OS and the OS they run on. For example, I absolutely hate that there's no option in Firefox to only use the OS print dialog. Instead I am force to click print, then click "use system print dialog" every time. I seems to remember reading a bug report where Firefox deemed this intentional and wontfix. After all, if you leave Firefox to print something, maybe you won't ever come back and start using your print dialog to surf the web!
