Quest pop up questions etc

so when i do a world quest or any quest there’s always a pop up when i come into the area is there a way to remove that from happening? or when you kill a dungeon or raid boss, and that thing pops up that tells me i killed the boss can i get rid of that pop up msg what would those even be called its super frustrating having to right click it off every single time i do something and sometimes now in raids boss abilities will be on the screen that i cant click off they are in the chat log and on the screen
