What does a script blocker do to a web browser?

A script blocker is a browser extension or feature that specifically targets scripts running on web pages to enhance user control over their browsing experience. The primary functionality of a script blocker is to allow users to block, allow, or manage the execution of scripts from various sources on the websites they visit. This is particularly important because many web pages use scripts to load ads, track user behavior, and perform other tasks that some users may find intrusive or unnecessary.

By providing this level of control, script blockers can help reduce the amount of unwanted content, improve page load times, and even enhance security by preventing potentially malicious scripts from executing. Users who prioritize a clean browsing experience or who are concerned about privacy can benefit significantly from being able to choose which scripts they wish to enable or disable.

The other options do not accurately describe the main function of a script blocker. Rather than enhancing overall browser speed or blocking all Internet access, which limits functionality, the focus of a script blocker is mainly on the management of scripts. While improving user privacy can be a secondary benefit of using a script blocker, the central purpose of the tool is to provide control over which scripts run on the browser, making option C the most accurate.
