Show HN: I made a free Chrome extension that highlights recipes on food blogs (chrome.google.com)

I wanted to learn how to make an extension, so I took a hint from a discussion here: https://news.ycombinator.com/item?id=15745914

It's open source: https://github.com/sean-public/RecipeFilter

I hope everyone finds it useful; I know I already learned a lot in getting it on the Google Web Store!
