I really liked the add-on, is very useful for you to know when the next episode of an Anime will be online. The add-on also add the crunchyroll link to watch the episode. The problem is the security, because the Firefox require signed add-on, and this don't have.
sorry for the late reply on the Firefox store. Just informing you that this has been fixed long time ago! It also supports the newly released Firefox Quantum. Let me know if it works for you!
