NetBrain Extension is a browser extension developed by NetBrain. It is designed to be used with the NetBrain IE product and offers a convenient solution for avoiding the opening of duplicated pages.

The main feature of this extension is its ability to check whether an opened page matches the new page to be opened based on filter criteria. If a match is found, the extension will keep the opened page for the next actions and prevent the new page from being opened repeatedly. This helps to improve efficiency and avoid unnecessary duplication of information.

With NetBrain Extension, users can streamline their browsing experience by eliminating redundant page openings. This makes it a valuable tool for anyone using the NetBrain IE product, particularly those who frequently navigate through multiple pages. The extension is available for free on the Chrome platform and falls under the category of Browsers with a subcategory of Add-ons & Tools.
