My favorite desmos chrome extension of all time. This allows you to do so many interesting things like directly modify equation data or export smooth videos of things that are usually way too laggy for desmos to animate normally. Sometimes a desmos update will cause certain things to break but its maintained pretty well in my experience.

Can't use desmos without this

Great addon! Strange choice making Ctrl+Q the button to duplicate though, could lead to some headaches if it weren't for firefox's confirmation box.

Had been waiting for the Firefox release of this awesome extension. Same good features found in Chrome. I specially like the QOL features to empty and fill folders. Also, the video creator feature is a no-brainer for smooth animations.
