Firefox 20 will be available to download later today, as version 21 moves into Beta testing. It has two major new features – per window Private Browsing, and a new download manager.
Private Browsing allows you to use the internet without your browser saving any information, cookies and so on from sites you visit. In Firefox 20, you can open a Private Browsing window while keeping your other normal window open, a feature already available in Chrome.
Here’s how it worked when first introduced to the Nightly Build last year:

The new download manager is a bigger deal, as Firefox’s old manager was really in need of a refresh.
Firefox 20 adds a neat download button next to the Home button, which shows you the last three downloads when clicked. The icon changes to a progress bar when you are downloading. Clicking ‘Show All Downloads’ opens a new window, but with a completely redesigned ‘panel based’ download manager.
