The Mozilla Project has released Mozilla 1.7,
an open source web browser, chat and e-mail client that supports
XML, CSS, XSLT, XUL, HTML, XHTML, MathML, SVG, and lots of
other crunchy XML goodness. It's available for Linux, Mac OS
X, and Windows.
Version 1.7 improves popup blocking, lets users review and open blocked popups, supports multiple identities in the same email account, provides a "show passwords" mode that displays saved passwords, and makes various other small improvements. It also has some small but significant performance optimizations.
