The 2020 browser wars heat up as Google and Microsoft fight for a bigger share of the browser market. Google has started to heavily promote Google Chrome to Microsoft Edge users. Microsoft has started using Windows 10 to advertise Edge in the Start menu and Windows Search results. Microsoft also uses Bing to show warnings when users search for Chrome. Google is using the browser’s ‘user-agent’ string to identify all Edge users visiting these services and to display a warning message suggesting a Chrome switch. Microsoft is also promoting the new Edge browser in Bing when people search for Google Chrome.
