The latest test version of Firefox is called Deer Park and it bring to light many improvements to Firefox that users should love.

The Firefox development team is very keen to implementing features that are impacting and meaningful and it looks like the new version, Deer Park, won't disappoint.

This is an alpha version, which means unless you want to risk everything you've built into Firefox, you shouldn't use it.

There are three new features that look to really help Firefox expand it's base:

1. Sanitize. This feature allows you to remove personal data from your browser such as cookies, cache, browsing history, form information and other information. You can customize what to remove and how to remove it. This could eliminate the need for third part utilities.
2. Fast back. This is termed as experimental and boasts that you can quickly walk through the history of the sites you've visited.
3. Report broken websites. This is an interesting feature. Through a single mouse click you could report to a centralized database sites that don't work with Firefox. This is an great concept and leverages the millions of people using Firefox.

Each of these features is something new to Firefox Deer Park and should enhance anyone's browsing experience.
