It does what it says, but isn't there more important things that Mozilla can do to help prevent online harassment and just make the internet a better place overall than just replacing words?

finde ich gut!

I love this!
Derogatory words are everywhere, even a comment on social media. With this extension the negative energy from feeding with insults and bad words are gone. It actually affects to hear insults in real life as much as online. Thank you Mozilla for this excellent extension!

I like this a lot!
Is it possible to add other languages than english and german to filter bad words?

As seen in the screenshot, the word B!tching isn't filtered to Bossing.

FIXED IT - thank you Firefox :)
