Does the Mozilla browser even support CSS?
Very few of my stylesheet formats work in Mozilla.

Is there a local stylesheet that is overriding my stylesheet?
If so, is there an option to turn off the local stylesheet?

Also, I would treat Mozilla like Netscape 4.x in my PHP code; however, I
can't see in the user agent (shown below) any way to
determine that the browser is Mozilla. I've seen other browser
user agents with "Gecko" in them and those browsers do support style sheets.

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007

Of course - better than most (all?) other browsers.

Then you are probably doing something wrong. Supply a URL and perhaps
somebody can point the problem out to you. A common problem is serving
your stylesheets with the wrong content-type. Alternatively, you can check
your HTML and CSS for syntax errors here:

<URL:http://validator.w3.org/>
<URL:http://jigsaw.w3.org/css-validator/>

There are three types of stylesheet - author stylesheets, user stylesheets
(which Mozilla won't use unless you explicitly configure it to), and
user-agent stylesheets (the default presentation). These /cascade/
together (hence the name Cascading Style Sheets) to give the final
presentation.

It's very unlikely that a user stylesheet or user-agent stylesheet is the
source of your problems.

Why? There's practically no common behaviour between them.

Gecko is the rendering engine used by Mozilla, Firebird, Netscape, etc.
Gecko is the piece of software that applies stylesheets, so you are
probably just looking at different versions of Gecko.

If I had to guess, I'd say that you are serving your stylesheets with an
incorrect content-type, and they only get applied by older versions of
Gecko, or it varies depending on whether you are kicking it into "quirks
mode" or "standards-compliant mode". Supply a URL if you can't figure it
out by yourself.

User-agent sniffing is usually a case of trying to fix the symptom and not
the problem. Apart from anything else, it's inherently unreliable and
should only be used as a last resort.

One of the best.

Probably something wrong with your stylesheet then. Post a URL of the
web site in question so we can check it out.

Only if you (or whomever uses this particular copy of Mozilla) have
set one up. Look for a file called user.css

NN4.x is an antique dinosaur with many, many bugs and deficencies.
Mozilla is a cutting edge, state of the art browser with some of the
best support for web standards around.

Gecko os the name of the rendering engine used in Mozilla, Netscape
6+, Camino, etc., etc. They all render pages much the same.

Yes, of course -- and rather better than most of the the
alternatives.

URL? Details? (Please validate your stylesheet at
<http://www.htmlhelp.org/tools/csscheck/> and fix any errors first.)

Take a different approach, because you can't rely on what you are doing.

For example, many people use Norton Internet Security, and it has a
'Browser Privacy' option:
Browser Privacy prevents Web sites from learning the type of computer
and browser that you are using, the Web site that you last visited,
and other information about your browsing habits
and that's just an example of what "non technical people" can do.
Many people can, and do, make their browsers appear to be other than
what they are actually using, for a variety of reasons.
