how do I indicate SM as Firefox
Do you just want to "advertise Firefox compatibility"? In that case:
Edit | Preferences | Advanced | HTTP Networking:
[x] Advertise Firefox compatibility.
This will get you a user agent string that includes both SeaMonkey and
Firefox versions, like this:
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0
But if you want to "spoof Firefox" by pretending to be using that and
eliminating all mention of SeaMonkey, you need one of the other options
for modifying the UA string, such as the various add-ons or
configuration settings. Others are more expert on those than I.
