A lightweight web browser is a type of internet browser designed to use fewer system resources, such as memory and processing power. These browsers are ideal for older computers or devices with limited hardware capabilities, allowing users to browse the web efficiently without slowing down their system. Examples of lightweight web browsers include Midori, Pale Moon, and Opera Mini. They often come with fewer features than standard browsers, focusing on speed and simplicity. This makes them suitable for users who prioritize quick access to websites over advanced functionalities.
