Having trouble updating firefox on my mac

more options

I have firefox on my mac and it hasn't been upgraded or used in several years. I followed directions, but have not been successful at upgrading. It asked me to restart, which I did, but then nothing happened. I don't know what is going on.

If you can't update, via the Firefox about page, try downloading manually downloading the newest version of Firefox from here.
