"American Express says they support Firefox."  Their Web server may be
attempting to detect what browser you are using.  This is called
"sniffing".  In too many cases, servers sniff for "Firefox" when they
should instead sniff for "Gecko".  That's because the component that
requests and displays the Web page is the Mozilla Gecko rendering
engine, which is used by both Firefox and SeaMonkey (although SeaMonkey
uses a version of Gecko that is one step behind Firefox).  See
<http://wiki.mozilla.org/User:Sardisson/Gecko_is_Gecko> for details.

One way to test my conjecture that sniffing for "Firefox" is involved is
to make the server think you are indeed using Firefox.  This is called
"spoofing".  There are two major ways to do this.

You can install an extension such as PrefBar or UserAgentSwitcher from
Mozdev.  Use the installed extension to spoof Firefox.

You can change your user agent string manually.  (See
<http://www.rossde.com/internet/intr_gloss.html#agent> for a definition
and example of "user agent".)  Search in MozillaZine at
<http://www.mozillazine.org/> for advice on doing this.

If either of these solves your problem, then please (1) report it as a
bug and (2) notify American Express.  To report a bug, go to the
American Express site; then, on the SeaMonkey menu bar, select [Help >
Report Broken Web Site].  The best way to notify American Express would
be a letter (postal mail) to the CEO; minimize (but don't eliminate)
technical jargon and include a reference to the
<http://wiki.mozilla.org/User:Sardisson/Gecko_is_Gecko> Web site.

Go to Mozdev at <http://www.mozdev.org/> for quick access to
extensions for Firefox, Thunderbird, SeaMonkey, and other
Mozilla-related applications.  You can access Mozdev much
more quickly than you can Mozilla Add-Ons.
