Mozilla have released Firefox 16 and is now available for download. For those who uses Firefox you can update your browsers to version 16.0 by clicking through the Firefox button > Help > About Firefox. You can also download it via the official download page. Anyway, so what is new with Firefox 16? I have already updated my Firefox browser and UI-wise nothing seems to have changed. But what is amazing is that Firefox 16 has preliminary support for the Mozilla Marketplace. I went to the site and yes it is preliminary alright. The site said that it is currently only available to invited Mozillians.
