Mozilla has released Firefox 20 for Mac users, and this major update brings several new features and improvements to the web browser. Two of the biggest features are “per-window” private browsing and a redesigned download manager.
You can now open a private browsing tab instead of having to open an entirely new window and close the current session. The new, Safari-like download manager is a little arrow that sits in the browser’s toolbar next to search. You can click it to see and interact with all current downloads.
Mozilla has also added the ability to customize the shortcuts for favorite sites on the home screen. Buggy plugins can be killed independently, which means that Firefox will finally stop crashing every time something goes wrong.
There are a lot of other stability and support additions in this release, so be sure to grab Firefox 20. The update will be downloaded in the background if you already have Firefox installed on your Mac.
