Mike, if you're interested in resolving your Firefox issues, I suggest the following.
First, leave stunthanger.com by logging off. Make sure that you are NOT viewing stunthanger.com in any way. Then do the following. These steps will completely clear your system of all traces of stunthanger.com and will then let you re-initialize it when you then later visit the site again.
1) Open Firefox and bring up the "Preferences" window. Not sure where that is on a MAC, it's on the Edit menu on my Linux system, and I understand it's a Tool item on Windows.
2) On the Privacy tab, set the "Firefox will:" to "Use Custom Settings for history"
3) Make sure the "Accept cookies from sites" is checked.
4) Click on the "Exceptions" button to bring up the list of sites. If "stunthanger.com" and/or "
www.stunthanger.com" are present, highlight them and then click on the "Remove site" button.
5) Back on the Preferences window, click on the "Show Cookies..." button. Find and delete all cookies associated with stunthanger.com
Probably best to also clear the cache. Not sure if it's the same on all flavors of FF, but on my Linux system it is done be visiting the "Advanced" tab of the Preferences window, where there is a "Clear now" button associated with "Cached Web Content".
Now stop and restart Firefox and go to stunthanger.com. The site should appear as a totally new site to your Firefox browser, and it should properly set cookies, etc. to work as you want.
Hope this helps.
(And I hope this is all correct! Suggestions/corrections/etc./ are welcome.)
