I have an old desktop Mac G4. I have used Firefox for many years. I acquired an iBook G4. I had Firefox all set up on it but recently did something foolish and lost all my preferences. I've managed to re-import my bookmarks from the desktop computer to the laptop computer (that's relatively easy) but I cannot find any way to export or import preferences, including saved passwords, cookies, configuration &c from the desktop machine to the laptop. I'm sure there has to be a way to do this but it's not obvious.
