Keyword Blocker is a free Chrome extension designed to help users avoid unwanted websites by blocking pages containing specified keywords. This tool is especially useful for individuals looking to enhance their browsing experience by filtering out content that may be distracting or unwanted. Upon installation, users can easily manage their blocked keywords through a straightforward interface, allowing for quick entry and immediate effect on browsing behavior.

The functionality of Keyword Blocker is straightforward: once a keyword is added, any website URL containing that keyword is automatically closed. This feature ensures that users do not encounter sites they wish to avoid. However, it’s important to note that once a keyword is added, it cannot be removed, which is an intentional design choice. For users concerned about the permanence of their settings, it is advised to use Registry Editor for added security.
