FireFox 42 Released With Privacy and Developer Tool Improvements

Mozilla has released its latest version of FireFox, version 42 to bring us better tracking protection in its private browsing mode.

The new feature has been tested in its developmental and beta channels since August and has since, been working its way into this production deployment of FireFox 42.

The new tracking protection now blocks content from a huge list of domains which are provided by Disconnect which have been known to track users on the Internet.

“We’re releasing a powerful new feature in Firefox Private Browsing called Tracking Protection. We created this feature because we believe in giving you more choice and control over your Web experience. With the release of Tracking Protection in Firefox Private Browsing we are leading the industry by giving you control over the data that third parties receive from you online. No other browser’s Private Browsing mode protects you the way Firefox does—not Chrome, not Safari, not Microsoft Edge or Internet Explorer.” Firefox team said in a blog posting today.

In addition to the tracking protection, some other features include HTML source code for web pages will now open in a new tab rather than a window. Tabs will also indicate which tab is playing audio and allows for muting them by clicking the little audio icon on each tab. The developer tools has also undergone a lot of changes that include animation tools and allows for developers to really dive into the web code to understand how it works and how it flows. Here is a quick video on the new FireFox Developer Edition;

One of the coolest developer tools that I found is the memory snapshots that allows you to see and understand how memory is retained and allocated. The tool works by taking a snapshot of the heap, then allows you to drill down by retained object type, allocation stack, or internal representation.

There is also a WebSocket Debugging API that gives a path to a full fledged Web Socket inspection tool but nothing official is out. Developer Tools engineer Jan Odvarko has created an experimental addon, for inspecting WebSocket traffic but its definitely Alpha but Mozilla is looking for users to try it and give feedback.
