Dale a Firefox el aspecto de Google Chrome

Me gusta el look de Google Chrome, pero por desgracia aun no esta disponible para Linux, asi que estaba usando la emulacion mediante wine que proporciono crossover. Esto tiene un problema, muchas veces me “peta”, y tengo que reiniciarlo.
Asi que me dije, ¿sera posible darle a Firefox el look de Google Chrome en todos o la mayoria de aspectos?. Y la respuesta es: “si”. Si mirais la captura de pantalla, ese es mi Firefox, no es un 100% Google Chrome-Look, pero se asemeja bastante, a mi me vale y ademas tengo toda la potencia de ciertos plugins de firefox que vengo usando. Si te interesa tenerlo igual, vamo a ver los pasos que tenemos que dar. Me he basado para este articulo en el post Turn Firefox into Google Chrome de LifeHacker (pero añadiendo cosas de cosecha propia ^^).

- Lo primero que hacemos es instalarnos la extension Chromifox, con eso ya tenemos practicamente el look de Chrome en Firefox, tras reiniciar.

- Existe otra buena extension: ChromiGlass, pero esta requiere que estes registrado para poder descargarla y ademas solo es valida para Windows. Nosotros pasamos de ella, ademas, usando Emerald y Compiz podemos conseguir el mismo efecto de transparencia.

- Ahora instalamos la extension: New Tab button on tab.

- Instalamos tambien la extension: Hide Menubar. Ojo que al instalarla, desaparece la barra de menus, dandonos mas espacio para navegar. Si queremos volver a visualizar brevemente la barra de menus, tenemos que pulsar la tecla “Alt”

- Vayamos ya al ultimo paso, subir la barra de pestañas al top, es decir a la parte de arriba de la pagina de Firefox, de manera que primero tengamos la barra de pestañas y despues la barra de navegacion. Para que quede bonito, tendremos que hacer uso de la extension Stylish, que instalaremos previamente.

Una vez instalado Stylish aparece en la parte inferior derecha de firefox un nuevo icono, que nos permite gestionar los scripts instalados y activos de Stylish. pues bien, pulsa ahi y crea un nuevo script (Administrar estilos…) llamado por ejemplo “tabtop”, el contenido de este script lo puedes encontrar aqui en este enlace, que viene a ser el siguiente:
