Es una buena extensión, pero sin duda incompleta.
Si bien deja personalizar casi todos los aspectos de las pestañas, no tiene la posibilidad de modificar el fondo de ''nueva pestaña'' por lo que se queda en blanco. Si tienes todo oscuro o trabajas de noche acaba siendo bastante molesto y casi obligandote a no usar diseños personalizados para ponerlo en modo oscuro.

Why have I never known about this?! Totally changes the game. Simple add on with of customization and control.

needs to improve because you only can change few things

This extension is great! Love the simple concept, UX, and tools to colourize Firefox the way I'd like!

However, I really REALLY don't like that it overrides the dark theme on the new tab page. (And why only on the new tab page? Why not also override the settings pages and stuff?) If I disable the extension, then the new tab page goes back to having dark mode.

Really, this extension should respect default behaviour by showing whichever theme my OS is set to for Firefox pages... then allowing me to choose to override that theme by selecting colours for the new tab and settings pages. That would make this extension PERFECT! :]

super bueno lo malo es que no me deja poner extension osea un fondo

!

Little bit hard to understand first but once you understod it, it was amazing! <3
