The brand-new Mozilla Firefox 23 web browser will be officially announced by Mozilla later today, but you can download the final version right now (see download link at the end of the article) from the official Mozilla FTP servers. Among the highlights of Mozilla Firefox 23.0 we can mention that mixed content blocking has been enabled to protect users from eavesdroppers and man-in-the-middle attacks on HTTPS pages, the about:memory’s functional UI (user interface) has been improved, the notifications of plugin installation has a simpler interface, and social share functionality has been added.
