What is this plugin/addon called?

What am I looking at

if you are talking about the icons it’s silkicons, otherwise i have no idea

It’s clearly a chat box but he whited out the text… Idk how you guys can’t see it.

From what I can tell, its a custom chatbox. I want to say what ever server you were In, wants to keep if for them self (It was made only for them)

Oh you mean this one?
