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 }, { -brand-name-edge }, { -brand-name-brave } and { -brand-name-opera } work on all major systems and are easy to install, { -brand-name-ie } 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-brave }, { -brand-name-edge } and { -brand-name-opera } can easily be installed and even used side by side.
Prva stvar koju treba istaći je da neće svi pretraživači raditi na svim operativnim sistemima. Iako su { -brand-name-firefox }, { -brand-name-chrome }, { -brand-name-edge }, { -brand-name-brave } i { -brand-name-opera } dostupni na svim glavnim operativni sistemima, { -brand-name-ie } i { -brand-name-safari } će raditi samo na { -brand-name-microsoft } ili Apple-ovim sistemima. Apple mobilni uređaji dolaze sa unaprijed instaliranom { -brand-name-safari } verzijom za mobilne uređaje, dok većina { -brand-name-android } uređaja dolazi sa unaprijed instaliranim pretraživačem prilagođenim proizvođaču. { -brand-name-firefox }, { -brand-name-chrome }, { -brand-name-brave }, { -brand-name-edge } i { -brand-name-opera } se lahko instaliraju i mogu čak da se koriste uporedo.
