On more than one occasion I have accidentally closed down Mozilla by selecting "File" and then "Exit" while I'm in the Manage Bookmarks window. As this window has a different menu layout from the browser itself, I keep thinking of it as being somehow 'seperate' from the browser, and that by selecting Exit I am just exiting from the MB window. I realise that there is a "close" option as well, but it doesn't stop me from making the same mistake. Would it be possible to at least bring up a warning box when "exit" is selected here, along the lines of "Exit Mozilla and close all open browser sessions" or something?

this is really a dup of bug 39057 (from when it was called "quit" instead of "exit")

Verified dup.
