developing a site thru DW and previewing it in my standard browser(s). When I preview it in : Safari/IE/Opera/Chrome the site appears as I'd like it. However, I'm getting a bit of issues with firefox. Why is this happening?
It's an incorrect recommendation that you recommend that he use XHTML transitional because 'that's what everybody else is using'.
I used to use XHTML doctypes (strict almost exclusively) but then somebody (on this forum, I can't remember who) pointed out why not use HTML strict? What is using the XHTML allowing me to do with my pages that I can't do with HTML?
I suggest the OP think about the same things and do the research to find the answers when creating his page(s).

As far as web pages are concerned XHTML allows your users to more easily write programs that monkey with the page, extracting the information that is relevant to them. Away from the web it allows you to combine mark up languages. You pay, however, because XHTML is incompatible with HTML and HTML browsers.
This can become a big problem because behind the scenes your web server is telling browsers what type of document is being sent. And if the browser is expecting HTML and it gets XHTML things can get ugly. Oh, and MSIE doesn't understand XHTML as a type of HTML. It understands it as raw XML which is not an incorrect thing to do.
If you must use XHTML then you must follow the XHTML HTML Compatibility Guidelines. But if you are a Dreamweaver user, those guidelines will make no sense whatsoever so do use HTML 4.01.
