By Akhil Nair in Google Chrome.Prevent Duplicate Tabs is a Chrome extension that prevents you from opening multiple tabs of the same site. The extension can ensure that there is only a single page open of a particular domain or that there are no duplicate URLs open across any one window.

The extension adds an icon next to the URL bar that can be clicked to toggle between the modes or to deactivate the extension. When the icon arrow is green, the extension will prevent duplicate URLs from opening. If you already had two pages from the site before switching to this mode, the previous tabs will not close, however, if you open a new link from the same site, the new link will open and all previously opened links from the same domain will be closed.
