Change which web browser opens websites by default
When you click a link to a web page in any application, a web browser will automatically open up to that page. However, if you have more than one browser installed, the page may not open up in the browser you wanted it to open in. To fix this, change the default web browser:
Open the Activities overview and start typing Details.
Click on Details to open the panel.
Choose Default Applications from the list on the left side of the window.
Choose which web browser you would like to open links by changing the Web option.
When you open up a different web browser, it might tell you that it’s not the default browser any more. If this happens, click the Cancel button (or similar) so that it does not try to set itself as the default browser again.
