Tab Closer is a free Chrome extension developed by Sander Sluis. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

Tab Closer allows you to opt-in for a developer to programmatically close tabs. This feature is particularly useful in enterprise environments where closing tabs is necessary for security purposes. For example, when a user logs out, the extension can automatically close the tab to ensure that sensitive information is not left open and accessible.

By installing Tab Closer, users can have peace of mind knowing that their browsing sessions are more secure. With this extension, the developer is granted permission to close tabs programmatically, adding an extra layer of protection to their online activities.
