How to : Install Latest Firefox 50.0 Beta 9 on Ubuntu 16.10, Ubuntu 16.04 and Ubuntu 15.10

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.

Easier Browsing

Mozilla put of a lot of resources into creating a simple but effective UI aimed at making browsing quicker and easier. They created the tab structure that has been adopted by most other browsers. In recent years Mozilla has also focused on maximizing browsing area by simplifying toolbar controls to just a Firefox button (which contains settings and options) and back/forward buttons. The URL box features direct Google searching as well as an auto predict/history feature called Awesome Bar. On the right side of the URL box there are bookmarking, history and refresh buttons. To the right of the URL box is a search box which allows you to customize your search engine options. Outside of that a view button controls what you see below the URL. Next to that you have the download history and home buttons.

Speed

Mozilla Firefox boasts impressive page load speeds thanks to the excellent JagerMonkey JavaScript engine. Start up speed and graphics rendering are also among the quickest in the market. Firefox manages complex video and web content using layer-based Direct2D and Driect3D graphics systems. Crash protection ensures only the plugin causing the issue stops working, not the rest of the content being browsed. Reloading the page restarts any affected plugins. The tab system and Awesome Bar have been streamlined to launch/get results very quickly too.

Security

Firefox was the first browser to introduce a private browsing feature which allows you to use the internet more anonymously and securely. History, searches, passwords, downloads, cookies and cached content are all removed on shutdown. Minimizing the chances of another user stealing your identity or finding confidential information. Content security, anti-phishing technology and antivirus/antimalware integration ensures your browsing experience is as safe as possible.

Personalisation & Development

One of the best features of the Firefox UI is customization. Simply right click on the navigation toolbar to customize individual components or just drag and drop items you want to move around. The inbuilt Firefox Add-ons Manager allows you to discover and install add-ons within the browser as well as view ratings, recommendations and descriptions.

Site authors and developers can create advanced content and applications using Mozilla’s open source platform and enhanced API.
