What is the role of themes in web browsers?

Themes in web browsers play a vital role in modifying the visual appearance of the browser itself. They allow users to customize their browsing experience by changing the look and feel of the interface, which includes aspects like colors, background images, and overall design elements. This personalization enhances user satisfaction, making the browser more visually appealing and comfortable for individual preferences.

Unlike other functionalities related to browser security, cookie management, and web page loading speeds, which focus on performance and security aspects, themes specifically address the aesthetic component of the browsing experience. This customization can help users express their individuality and enhance their enjoyment while using the web.
