MouseNav is a free Chrome add-on developed by KoalaBear that enhances your browsing experience by allowing you to navigate through web pages using your mouse buttons. With MouseNav, you can use your right mouse button to navigate forward and backward, and the left and right mouse buttons together to perform a forward action.

The add-on offers a simple and intuitive navigation system. By pressing and holding the right mouse button, then pressing and releasing the left mouse button, you can easily navigate back. Similarly, by holding the left mouse button, then pressing and releasing the right mouse button, you can navigate forward.

MouseNav also includes additional features for video playback. For example, when double right clicking on a video, the add-on checks for video content, allowing you to still perform left and right swipes on videos without triggering any navigation actions.

Overall, MouseNav is a useful Chrome add-on for those who prefer mouse navigation over traditional methods. It provides a convenient way to navigate through web pages and enhances the browsing experience.
