What is the primary advantage of using Browser Extensions?

Using browser extensions primarily improves the functionality of the browser by adding extra features that enhance the user experience. Extensions can provide tools for blocking ads, managing passwords, capturing screen content, or integrating various web services directly into the browsing experience. This added functionality allows users to customize and optimize their browsing environment according to their specific needs and preferences, making their web interactions more efficient and tailored.

For instance, an extension might provide quick access to a productivity tool, help automate repetitive tasks, or incorporate additional search capabilities directly in the browser. These enhancements enrich the basic capabilities of the browser, making it a more powerful tool for users.

While other options touch upon aspects of browser performance and security, they do not capture the primary role of extensions as effectively as the improvement of browser functionality.
