I noticed the same with Nexus 7 (android) and firefox. On the desktop 
Ctrl + - usually makes things smaller and thus fit onto the screen (esp. 
editor right next to the world, so the controls below the world are 
visible), but on the android tablet that didn't help.

These tablets are just to small for all the information and even firefox 
is different compared to its desktop version.
