Firefox shows the mobile version of a website by default, but starting with version 3.1, you can easily change it to desktop view:
- Open Firefox and go to the website you want to visit.
- Click the menu button on your Fire TV remote.
- Click the desktop icon on the top right side of the screen. The page will reload in desktop mode.
Some websites are not optimized for both mobile and desktop. In these cases, Firefox will show only the available version of the site
