What is the primary function of a hub in a web browser?

The primary function of a hub in a web browser is to simplify browsing by organizing favorites and downloads. Hubs serve as a centralized location where users can easily access, manage, and organize their bookmarks or favorites, as well as keep track of downloaded files. This organization helps users quickly find the content they need without having to sift through various tabs or cluttered menus, providing a more streamlined and efficient browsing experience.

Other options touch upon important functionalities related to web browsers but do not specifically describe the role of a hub. Protecting user privacy often involves security features built into the browser but is not the main characteristic of a hub. Enhancing video playback relates more to the performance capabilities of the browser itself rather than the organizational functionality of a hub. Blocking unsolicited ads typically falls under the category of ad-blocking extensions or built-in features in browsers but doesn't relate to what a hub specifically does.
