A problem worse than Zoom

On macOS, an app can register to handle URL schemes. Web browsers such as Safari, Chrome, and Firefox register to handle the schemes for web pages, http or https. Non-browser apps may register to handle other URL schemes; for example, an email client may register to handle the well known mailto scheme. When a URL is opened in a web browser, and the browser itself cannot handle the URL scheme, the browser looks for another app to handle the URL. If there's a handler app for the URL scheme, then the browser will open the app and pass the URL along to that app. Thus, clicking a mailto:[email protected] link will open your email client with a new email addressed to Tim Cook.
