According to an IBM document ( http://www.ibm.com/developerworks/xml/library/x-ffox15.html ) XHTML 1.1 is supported by Firefox: "Mozilla Firefox 1.0 supports XHTML 1.0 Strict, Transitional, and Frameset, as well as XHTML 1.1 which is based on modularization of XHTML 1.0 Strict. XHTML 2.0 is still in the working draft stage. Some developers wonder how well XHTML 2.0 will be adopted because it's such a significant change from HTML and XHTML 1.x. I recommend that Web developers targeting Firefox (such as for embedded applications) serve XHTML 1.1. Unfortunately, this may not yet be practical for developers targeting the general Web."

XHTML is used as a stricter view of HTML. People who like to make the code clean and nice use XHTML.
XHTML 1.0 was established on January 26, 2000.
All modern browsers support XHTML.
XHTML stands for eXtensible HyperText Markup Language.
XHTML is a combination of largely HTML and a small portion of XML.
The requirement for a valid XHTML is that all the tags should be closed. This is actually the difference between HTML and XHTML.
HTML and XHTML are two different languages used for web and application design. XHTML was a popular choice from about the year 2000, to 2011. HTML 5 is intended to replace XHTML. XHTML followed the basic rules of XML-based languages. HTML (both prior and since) do not.
