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.

It earste wat jo witte moatte oer portabiliteit is dat net alle browsers op alle bestjoeringssystemen draaie. Hoewol { -brand-name-firefox }, { -brand-name-chrome } en { -brand-name-opera } op alle wichtige systemen wurkje en ienfâldich te ynstallearjen binne, wurkje { -brand-name-ie }, { -brand-name-edge } en { -brand-name-safari } allinnich op de eigen systemen fan { -brand-name-microsoft } en Apple. De mobile ferzje fan { -brand-name-safari } is yn it foar ynstallearre op de mobile apparaten fan Apple en de measte { -brand-name-android }-apparaten wurde levere mei in yn it foar ynstallearre browser dy't troch de fabrikant foar it apparaat oanpast is. { -brand-name-firefox }, { -brand-name-chrome }, { -brand-name-edge } en { -brand-name-opera } kinne ienfâldichwei ynstallearre en sels neist inoar brûkt wurde.
