Mozilla Firefox Version 26.0 Released


Mozilla sent Firefox Version 26.0 to the release channel.  At the time of this posting, no security fixes for this version have been listed in the Security Advisories page.  However, the default for Java plug-ins to "click to play" is a welcome change as is script-generated password fields.

Update:  The security updates have now been posted.  Version 26.0 includes five (5) critical, three (3) high, three (3) moderate, and three (3) low security updates.
