The thing is highly outdated to the actual downloaded version. I tried to use it, but it is very cluttered and with the ads I can't even see my entire screen. I would not recommend it for professional use. I would recommend it if you are bored and want to mess around with drawing for a little, but even then I found .io websites that are better than this extension.
