If a link opens in a certain app rather than in the browser e.g. a link to Facebook page or a Tweet, you could find yourself waiting around while your phone shuts down Chrome before it loads something else. You can avoid this by:
Going to Settings > Apps
Finding the app that keeps opening.
Scrolling down to Open by default, select it.
Selecting Clear Defaults.
If that fails, do the same with your browser app as well.
