Pues no sabía que se podían agregar vistas personalizadas y atajos de teclado para cada una. Para pantallas grandes está muy bien. Otro de mis imprescindibles.

Well, just a few days ago, Firefox Nightly started to act weird on my machine. One of the problems are web pages getting suddenly too large for my screen (with a scroll bar appearing at the bottom). This add-on fixes at least that problem for me. Many thanks !
