Mozilla Firefox 48.0 is Available, Install on Elementary OS / Linux Mint / Ubuntu Based

The Mozilla Firefox project is a redesign of Mozilla's browser component, written using the XUL user interface language and designed to be cross-platform, supporting Linux, Android, Microsoft Windows and Mac OS X operating systems. It is a fast, small and very easy-to-use web browser/navigator/explorer that offers many advantages over other similar products, such as the ability to block pop-up windows and the feature-rich tabbed browsing experience.

Features at a glance
The application offers a well designed graphical user interface that integrates search (powered by Google, Bing, Yahoo, etc.), and industry leading accessibility with Find As You Type - find links and page text by simply typing. As mentioned before, the Firefox browser features comprehensive pop-up controls, which will keep unwanted advertising off your desktop. A tab browsing mode will let you open several pages in a single window, allowing you to load links in the background without leaving the page you're on.
