I have a 64 bit system, So I am going to download Firefox for my 64 bit OS from the Firefox download page at.
Finally, Firefox version 55 has been released on August 8, 2017, for all major OS e.g. The binary package are now available for download for Linux (POSIX) systems, grab desired one and enjoy the browsing with new features added to it.
New Firefox has also added a lots of new interesting features to Android as well.
It is based on the rendering engine of the Firefox web browser, Gecko, and on the Linux kernel. Firefox OS was designed to provide a complete, community-based alternative operating system, for running web applications directly or those installed from an application marketplace. Around the same time, it was reported that Acadine Technologies, a startup founded by Li Gong (former president of Mozilla Corporation) with various other former Mozilla staff among its employees, would take over the mission of developing carrier partnerships, for its own Firefox OS derivative H5OS.
The applications use open standards and approaches such as Java Script and HTML5, a robust privilege model, open web APIs that can communicate directly with hardware, e.g. The project proposal was to "pursue the goal of building a complete, standalone operating system for the open web" in order to "find the gaps that keep web developers from being able to build apps that are – in every way – the equals of native apps built for the i Phone, Android, and Windows Phone 7." The announcement identified these work areas: new web APIs to expose device and OS capabilities such as telephone and camera, a privilege model to safely expose these to web pages, applications to prove these capabilities, and low-level code to boot on an Android-compatible device. According to Ars Technica, "Mozilla says that B2G is motivated by a desire to demonstrate that the standards-based open Web has the potential to be a competitive alternative to the existing single-vendor application development stacks offered by the dominant mobile operating systems." The goal of these efforts is to enable developers to build applications using Web API which would then run in any standards compliant browser without the need to rewrite their application for each platform.
