The Xbox One allows you to browse the internet using the Internet Explorer browser, but it's not quite as practical as using a PC. You might consider configuring IE to open the mobile version of websites (better ergonomics and a simplified layout). To enable this option, follow the procedure below.
How to view mobile websites on the Xbox One?
- Open Internet Explorer.
- Press the Menu key of your controller > Settings.
- In the General section, check the Use webpages formatted for mobile devices tab.
