Mozilla Firefox is a fast, full-featured Web browser that makes browsing more efficient than ever before. Firefox includes pop-up blocking; a tab-browsing; integrated Google searching; simplified privacy controls that let you cover your tracks more effectively; a streamlined browser window that shows you more of the page than any other browser; and a number of additional features that work with you to help you get the most out of your time online.

Mozilla Firefox 2.0.0.12 fixes 11 security issues, three of which--Web browsing history and forward navigation stealing; privilege escalation, XSS, remote code execution; and crashes with evidence of memory corruption--are deemed critical.
