The Filter Manager allows to filter web sites for example to block advertisments, block tracking scripts and much more. iCab Mobile supports popular filter lists known from Desktop browsers (like Easylist, AdBlock Plus, uBlock and compatible) but also filters based on 'hosts' files. And users can also create and share their own self-made filters.
iCab Mobile provides a large list of popular filter lists to choose from, so no special knowledge is needed.
