Enter the following in the URL bar (without the quotes) "about:debug". It will look like nothing will happens. However, if you tap the icon in the notification bar with the three horizontal lines with the dots next to them, then select "more", then select settings, and scroll down near the bottom of the list you should now be able to see and select an option for "Select User Agent".

Once you change this setting the browser should load regular websites rather than the mobile versions.
