I have Mozilla on an older machine and 'Forum" is right there at the top in between 'Photos' and 'Hurricane'.Try these things first: - Have you verified that your computer is plugged in? - Have you verified that your computer is turned on? - Have you tried clearing out your cache? I don't know what this does but they're always recommending it. - Have you tried restarting your computer? If you have not, do that now. If you already have, do it again.
