sites without complaints about SM being out-of-date?

On what operating system? Windows, Mac or Linux?

Probably one with Firefox 84.0 which is the current version or Firefox 
78.0 which is the current ESR version.

YMMV

I use Firefox Nightly, but keep SeaMonkey around to help with the easy 
questions.

Reading between the lines, it looks like you're wanting a one-time 
set-and-forget setting that's set globally.  You can do that by going to 
about:config and setting general.useragent.override, and for that, I 
suggest using the stock UA for Firefox 78 ESR:

   Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:78.0) Gecko/20100101 
Firefox/78.0

This shows that you're using a 64-bit version of Windows 10, but if 
you're using something else, I don't think it really matters.  If you 
spoof the ESR version of Firefox (i.e. 78) , that should be adequate for 
most sites. If you use the most current version of Firefox, then you'll 
need to update each time Firefox does a new version.

However, there is nuance, and a few trade-offs, because how sites handle 
thing varies by site.  Consider:

1) If you do a global setting, then that applies to everything, 
including the mail client, if you use that.  The result is that your 
email messages show whatever you're spoofing, via the User-Agent: 
header.  It may not make any practical difference, but in the Grand 
Scheme of Things, it is odd if an email message shows that it was 
composed/sent with Firefox, rather than a mail client.

2) As a general thing, I want sites to know that I'm using Seamonkey 
(via what turns up in their logs), and where they're fine if I'm showing 
an acceptable version of Firefox.  Thus, by using site-specific settings 
via general.useragent.override.[example.com], I use:

   Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 
Firefox/68.0 SeaMonkey/2.53.5

There are sites that are beginning to complain about Firefox versions 
earlier than 78.0, and if I need, I can change 68.0 to 78.0.  Using this 
construct, I can spoof the sites that need it, without doing it globally 
(including not touching my email).

3) For www.google.com, I've found that when I'm using the normal 
Seamonkey UA, there's a display quirk, where google's search bar causes 
the cursor to display about half above the bottom of the search bar. 
The way around that is to set general.useragent.override.google.com to 
standard Firefox (without indication of Seamonkey), as noted above.  The 
effect of the quirk is minor, but it's nice to know that there's an easy 
workaround.  My impression is that there's other Google-related pages 
that don't like a Seamonkey UA (and where it's useful to do similar 
spoofing) but I don't use Google services often enough that I have any 
first-hand experience to know which they are.

4) I have seen evidence of sites not working with current versions of 
Seamonkey, regardless of what kind of spoofing you do.  A couple of 
months back, there was discussion of rottentomatoes.com, and in the 
context, I did check there, and found problems that I couldn't bypass 
with spoofing.  Apparently, they really do use some feature that's been 
added to more recent versions of Firefox.

I use Windows 10, 64-bit.

Thomas, a couple of days ago, in the thread "No access to Acronis site", 
Cecil Bankston indicated that he was getting around some Browser 
sniffing but just spoofing the Useragent string "Mozilla/5.0".

Could be worth a try!!

Tried it - Google appeared very different. I really have trouble with 
YouTube and Facebook when I try any spoofing so far.
