HN Rules: "Show HN is for something you've made that other people can play with. HN users can try it out, give you feedback, and ask questions in the thread." I thought the whole purpose of Show HN is to show what you've created. Should there be restrictions on the types of things being created? In your example, I think the browser extension would hide every submission on Show HN.
