Tabs Blacklist (Policies) is a Chrome extension developed by landel.gilles. This free extension is categorized under Browsers and falls under the subcategory of Add-ons & Tools.

The purpose of this extension is to automatically close tabs that have URLs listed in the blacklist. Tabs Blacklist (Policies) is capable of loading configuration from Chrome's policies, which includes the registry for Windows, JSON file for Unix and ChromeOS, and MCX for Mac.

This extension offers three matching modes to detect if a tab's URL is blacklisted: exact, contains, and regular expression. The exact mode validates if the tab's URL is exactly equal to one of the blacklisted URLs. The contains mode validates if the tab's URL contains any blacklisted text. Lastly, the regular expression mode validates if the tab's URL matches any blacklisted pattern.

Tabs Blacklist (Policies) automatically closes tabs with blacklisted URLs upon extension startup, tab creation/update by another extension, or by the user. After closing a tab, it tries to refocus on the previously active tab. Additionally, this extension includes a debug page that can be activated or deactivated through Chrome's policies.
