Desktops get a new Download Manager in Firefox 20 Beta.

Private browsing, or 'porn mode' for people with more prurient Web browsing requirements, will soon be available in Firefox on a per-tab basis.

The latest versions of Firefox 20 Beta (download for Windows, Mac, and Linux) and Firefox 20 Beta for Android (download) have been updated to allow people to choose private browsing on a per-tab basis. Private browsing disables built-in browser recording, including history and cookies.

This is a pretty big change for Private Browsing aficionados, since previously in Firefox switching to Private Browsing would save all your tabs, close the window, and open a new Private Browsing window without any previously-running tabs. The new behavior allows Private Browsing tabs to run side-by-side with non-Private tabs.
