Mozilla 1.0 <http://www.mozilla.org/releases/mozilla1.0.html> was released June 5, 2002 and already had support for XMLHttpRequest.
As for XSLT 1.0 support, it is also there since Mozilla 1.0 though scripting it is supported since 1.2 I think. See the FAQ for details and differences if you want to do client-side XSLT in both IE/Win and Mozilla: <http://www.mozilla.org/projects/xslt/faq.html>
There is also the Sarissa project: <http://sarissa.sourceforge.net/doc/> which aims to ease the task of XML/XMLHttpRequest/XPath/XSLT scripting across browsers.
