What is the "Internet box"??

I mean the router that comes with the modem my ISP provides.  The router,  
named Pace v5471, runs free software: https://github.com/alacn1/pace_v5471

It is surprising that Firefox properly renders the page but not Abrowser,  
which is a derivative.  I use the router in my Internet box and Abrowser  
properly renders its Web configuration interface.

The Web page to configure the router is probably badly formatted (invalid  
HTML or CSS): Firefox manages to bypass the issues, unlike some other  
browsers.  Sadly, many Web developers only care that Chrome, Edge/IE, Firefox  
and Safari properly display the page... if not only Chrome.

I would try to do what the guide says: click on what is supposed to be a  
drop-down menu, type tun0 and [Enter].  If that works, it is a terrible  
graphical interface: it should not be a drop-down menu, as you wrote.

It is supposed to open something and I should be able to choose tun0.

Te guide you link to does not say that.  It says:
type "tun0" at "Custom Interface" and press Enter
