Firefox 20 now available to download: New per-window Private Browsing and Download Manager!

After the released of Firefox 19 last February, Mozilla just announced that Firefox 20 is now officially available to download. Firefox 20 new features include a new per-window Private Browsing that allows you to open a new private browsing window without closing your current browsing session and a new Download Manager, so you can monitor, view and locate downloaded files without having to switch to another window. Firefox also comes ability to close hanging plugins without the browser hanging. More details after the jump.
