Bookmarklet Blocker is a free Chrome extension developed by Fun Apps that aims to prevent users from using bookmarklet exploits. This add-on is specifically designed for Google Workspace admins who want to enforce certain restrictions on bookmarklets.

Upon installation, Bookmarklet Blocker takes immediate action to ensure the security of the user's browsing experience. It deletes any pre-existing bookmarklets, effectively removing any potential vulnerabilities. Additionally, it also deletes any newly created bookmarklets, ensuring that users cannot create new exploits.

One of the key features of Bookmarklet Blocker is its ability to delete any bookmarks that users attempt to turn into bookmarklets. This further enhances the security measures, preventing any accidental or intentional misuse of bookmarklets.

The extension's source code is available on GitHub, allowing users to review and verify its functionality. It's important to note that Bookmarklet Blocker does not collect any user data, ensuring privacy and peace of mind for its users.

However, it's essential to exercise caution when using this extension, as once bookmarklets are deleted, they cannot be recovered. It is crucial to target the right audience and ensure that users are aware of the potential impact before implementing Bookmarklet Blocker. Future releases of the extension will introduce an allow-list feature, allowing admins to specify bookmarklets that should be exempted from deletion.

Overall, Bookmarklet Blocker provides a valuable layer of security for Chrome users, protecting against bookmarklet exploits and enhancing the browsing experience for Google Workspace admins.
