Just one needed particular GoDaddy web hosting account button link gives error in FF but ok in Pale Moon and IE

Question

Greetings:
I've searched but am unable to find a clue. Using Win 7 Home Premium (updates current) on HP DV3T-2000 64-bit.
Recently (possibly after upgrading to FF 14), on godaddy.com on my web hosting product page, clicking the 'Launch' button throws a godaddy error pg. All other launch buttons operate normally, as do 'all' the buttons (including the tricky one) in Pale Moon and IE.
I have several times cleared the cache and deleted all g-d cookies through options - show cookies; then closed the browser and restarted the machine. I then disabled all add-ons, tried the above again, no difference so have reactivated the plugins (which were and are current as to updates).
Here is the text from the godaddy error pg:
"Error
There was an error in the application. We apologize for the inconvenience. This error has been logged and reported.
Click here to go back to your account list."
The word above [Click] 'here' usually does not work either. Below is the url from the address bar: (When going to the url on a clean new tab, the error page pulls up without the 'Click here to go back to your acct list' ):
https://hostingmanager.secureserver.net/error.aspx?aspxerrorpath=/AccountPanel2.aspx
(However, people without a g-d acct will not be able to navigate to the web hosting product page.)
Thank you very much for your help.

Hi hedera, when you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
(You also can clear Firefox's cache completely using:
orange Firefox button ''or'' Tools menu > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now")
(2) Remove the site's cookies (save any pending work first) using either of these. While viewing a page on the site:
* right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
If you can't access the relevant domain without it closing, you can edit the domain at the top of the dialog in order to call up a list of its cookies.
Then try reloading the page. Does that help?
