I was prompted that my version of FF is old and followed prompts to download the new version. Once it downloaded, it instructed me to drag the icon onto my Aps icon and then drag it from there onto my doc. I have an iMac. There was no Firefox icon that showed up and when I opened Firefox to go on internet, it said I had an old version of FF and asked me to download. I did this twice. What is the current version? Under 'About Firefox', mine says 3.6.24. What to you think is going on? Thx.
