Prevent Duplicate Tabs is a powerful Chrome extension designed to automatically detect and close duplicate tabs, keeping your browser organized and efficient. It intelligently manages tabs based on URL matching, with customizable options to consider query strings and hashes. You can specify exceptions by adding hosts or URLs, ensuring certain sites are never auto-closed.

This extension also supports incognito mode without sharing data between normal and incognito sessions, maintaining privacy. Users can choose whether to close older tabs first and protect the currently active tab from accidental closure. With control over multiple tab events such as creation, updating, removal, and browser launch, Prevent Duplicate Tabs offers granular customization and quick enable/disable functionality without navigating the extensions panel, significantly enhancing tab management for all Chrome users.

User reviews

Users appreciate Prevent Duplicate Tabs for saving resources and managing tab clutter with a good interface. However, multiple reviews highlight issues: it occasionally blocks non-duplicates, closes original tabs causing data loss, waits for new tabs to fully load before closing duplicates, and lacks automatic switching to existing tabs. Users suggest improvements like better tab switching, avoiding reloads, and additional functions such as moving tabs. Overall, it is useful but has functionality drawbacks needing refinement.

Pros

Effectively prevents duplicate tabs, saving computer resources.
User interface is nice and easy to use.
Generally useful for managing multiple tabs and avoiding clutter.
Some users find it to be currently the best option in the store for this function.

Cons

Sometimes erroneously blocks non-duplicate tabs, requiring users to disable the extension.
The extension closes the original tab by default, causing loss of input data, which users find problematic.
It only closes duplicates after a new tab fully loads, so resource savings are minimal.
Does not automatically switch focus to the existing tab when blocking duplicates, making it hard to locate duplicates across many tabs or windows.
Reloads existing duplicate tabs when switching to them, which some users would prefer to avoid.

While I like the concept there were basically two major drawbacks that forced me to uninstall the extension. First and foremost was that it would occasionally erroneously prevent tabs that were clearly not duplicates from opening requiring me to disable it in order to access sites. Second as somebody else mentioned the tab must fully load before it then closes, so the saving of resources is actually quite minimal if any.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. 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.

Prevent Duplicate Tabs requires a few sensitive permissions. Exercise caution before installing.
