I don't know why I haven't discovered this extension before... ahh yes, I know. And it's just that, it's not in other browsers. I don't know why nobody else thought of developing such an extension in other browsers. It is most useful, as someone who has been cyberbullied many times, I am grateful to have found this extension because I will surely be cyberbullied more in the future (I don't know, I'm a target for bullies) but thanks to this I won't read their insults.
