The first thing to point out about portability is that not all browsers run on all operating systems. While { -brand-name-firefox }, { -brand-name-chrome } and { -brand-name-opera } work on all major systems and are easy to install, { -brand-name-ie }, { -brand-name-edge } and { -brand-name-safari } only work on { -brand-name-microsoft } and Apple’s own systems. The mobile version of { -brand-name-safari } is pre-installed on Apple’s mobile devices, and most { -brand-name-android } devices come with a pre-installed browser modified by the manufacturer for the device. { -brand-name-firefox }, { -brand-name-chrome }, { -brand-name-edge } and { -brand-name-opera } can easily be installed and even used side by side.
