TabGuard

TabGuard keeps your browser organized and efficient by automatically preventing duplicate tabs. When you open a tab with the same URL, TabGuard closes the duplicate and switches to the existing tab. This helps save memory, reduce tab clutter, and improve focus. It is ideal for power users, developers, researchers, and anyone who works with many tabs. The extension is lightweight, fast, and easy to use. No setup is needed; just install it and it works.
