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.

Installation instructions:

Mozilla does not provide a repository for its Firefox browser, but the installation steps are quite easy anyway and should not create difficulties on any Linux distribution.

The latest versions of Firefox are available as pre-compiled libraries via the Mozilla FTP, so we need to download the archive (i386 or i686 for 32 bit systems and amd64 or x86_64 for 64 bit systems), extract  it and run the firefox file. Also, it is advised to remove previous versions of Firefox, move Firefox to /opt and create a symlink, for an easier usage.

The below instructions should work on all the popular Linux systems, including Ubuntu, Linux Mint, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE, Linux Lite, Debian, Robolinux, SparkyLinux, Fedora, CentOS, OpenSUSE, Mageia, OpenMandriva, Arch Linux, Manjaro, ROSA Desktop etc.
