For desktop Linux enthusiasts, Firefox has not only been supported longer than Chrome, it offers a bit more flexibility in terms of its installation. The most common method of Firefox installation is to install it via your distribution’s package manager. However some distributions, such as Ubuntu, offer Firefox as the default browser, making any additional action from the user unnecessary.
The downside to the package manager installation approach is that you may not always have the absolute latest version of Firefox as it comes out. This is because you’re dependent on the release schedule provided by your Firefox package maintainer, not by you specifically. Because of this issue, I prefer to download a self-contained installation of Firefox instead. Once downloaded, simply extract to the location of your choosing, then run the executable. The advantage to using this approach is that you’re able to update Firefox from within the program itself.
