The Mozilla Project has released FireFox
0.9.1, an open source web browser for Windows, Mac OS X,
and Linux that supports XML, XHTML, XSL, HTML, and CSS.
Unlike the heavier weight Mozilla from which it is derived, this is just abrowser; no e-mail client, newreader, LDAP browser, or microwave oven is included. "This maintenance release provides a few updates based on user feedback - including changes to the Extension System and icon improvements."
