Private browsing is one of those long-sought features that everyone else has, and although Mozilla has been testing it for a while now, it’s one of the “big” features in the latest beta.
Besides private browsing mode, which lets you choose whether you want Firefox to retain possibly sensitive browsing data with one click, other new features compared to the 3.0.x Firefox branch include:
- ability to provide Location Aware Browsing using web standards for geolocation.
- Support for native JSON, and web worker threads.
- Improvements to the Gecko layout engine, including speculative parsing for faster content rendering.
- Support for new web technologies such as: HTML5
