A month ago I posted a review of add-on that has stopped working for me (AutocopySelection2Clipboard). I immediately got a reply of hate saying I was idiot. I reported that message and eventually it got deleted.
Now I noticed the developer insulted another user – https://addons.mozilla.org/en-US/firefox/addon/autocopyselection2clipboard/reviews/1761694/
Why Mozilla did not take any measures against that person? They continue insulting users.
