Features & Capabilities

Tab Deduper is a streamlined Chrome extension designed to automatically detect and close duplicate tabs to help you manage your browser workspace efficiently. Perfect for users who tend to open multiple tabs to revisit the same sites, this extension monitors URL changes in real-time. When it detects multiple tabs with the same URL within the same window, it activates one and gently closes the duplicates, reducing clutter and saving memory.

Inspired as a minimal alternative to the popular Duplicate Tabs Closer extension, Tab Deduper offers users customizable options to control its duplicate tab handling behavior. This ensures a personalized browsing experience, maintaining order without disrupting your workflow. With Tab Deduper, say goodbye to tab hoarding chaos and hello to a cleaner, faster browsing environment.

Is Tab Deduper Safe?

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.

Tab Deduper requires a few sensitive permissions. Exercise caution before installing.

Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
