Супер! Есть еще одно похожее расширение. Оно, правда, только с css умеет работать, но оно позволяет редактировать прям на той же странице в отдельной колонке.

Quería ocultar mis seguidores porque me hace seguir unas dinámicas muy tóxicas en Twitter... y he conseguido gracias a esta extensión ocultarlos. Por si os interesa, poned en el apartado CSS: a[href="/bolverkr/followers"] { display: none; } @Bolverkr es mi user, cambiadlo por el que queráis dejar de ver y listo. De nada.

This extension is the "Best of Breed" and very satisfying to use. I use it to * finetune some tools I use to my specific needs, * adjust tools certain groups of my colleagues use to better fit our processes and to * quickly sketch out changes/additions to our products which I recommend to my teams. I would be less capable, creative and certain about many things without it.

Thank you for the great stuff. I was using it to Japanese the ticker in Tradingview. I don't know if it was due to a recent Chrome update, but it suddenly stopped working. The code I had been referring to until then was the one described in the following blog. https://tecurio.com/trading-view-symbol-list-japanese-localization/ I am hoping to get it up and running again.
