Features & Capabilities

Smart Prevent Duplicate Tabs is a powerful Chrome extension designed to streamline your browsing by automatically preventing the creation of duplicate tabs with the same URLs. It intelligently closes repeated tabs based on customizable settings, such as whether to consider query strings or hashes, which tabs to close first (oldest or newest), and whether to protect your currently active tab.

The extension supports incognito mode with isolated tab management and features an easy toggle to activate or disable the add-on without accessing the extensions panel. Users can specify URL exceptions to preserve important tabs. It operates seamlessly by listening to various Chrome API events like tab creation, updates, replacements, and attachments, ensuring your browser remains organized and efficient.

A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
