Mozilla Firefox 23 brings social sharing button, mixed content blocker and network monitor

Mozilla has rolled out Firefox 23, the new iteration of its web browser for Windows, Mac, and Linux.

The new version of the browser is now available through the Firefox.com website. Existing desktop users will also be able to get the update through the browser.

The browser now sports a new logo and features a share button that lets users share a web page through a browser based dialog box, without the need to go to another web page. The sharing feature is enabled for Facebook. This is similar to Safari's sharing features, though it supports multiple services. The Firefox feature is based on Mozilla's Social API that makes it easier for web browsers to integrate with social media services.

The update also brings a Mixed Content Blocker. According to Mozilla, when secure HTTPS pages load additional content insecurely over HTTP (also known as Mixed Content), users are vulnerable to man-in-the-middle and eavesdropping attacks. The Mixed Content Blocker blocks insecure active content by default, protecting users from these attacks. Firefox automatically blocks mixed content and displays a shield icon in the address bar.

Firefox 23 also ships with a Network Monitor tool that allows users to track how long it takes for individual components of a webpage to load.
