What is one purpose of filters in web browsers?

Filters in web browsers serve the purpose of limiting the material that browsers fetch, which is essential for managing the amount of data and content that users encounter. This operation plays a significant role in tailoring the user experience by blocking unwanted content, such as advertisements, pop-ups, or potentially harmful sites. By employing filters, users can navigate the web more efficiently and with less distraction, allowing for a more focused browsing experience.

While speed enhancement, visual design improvement, and security in online transactions are important aspects of web browsing, they do not directly relate to the fundamental function of filters. Filters primarily focus on controlling the flow of information to improve user experience and safety while interacting with the web.
