Works very well for me on r3dfox/Firefox 144.0.1. I appreciate a lot the feature to load desired window size and position at startup as there's a bug on Firefox that doesn't allow it to remember these. With this extension it can be fixed and that's really enjoyable. Thanks to the dev!

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 !
