I love that this addon exists, but it does not work on IMDB.
11th Oct. 2024 update: the extension now works on IMDB, but it takes a few seconds before hiding the rating, so you have to keep your gaze away from the screen at first or you'll end up seeing the rating.
Hello, I have updated the Firefox port of this extension to the same version as the chrome version now (after failing to keep updated for a while now). All supported sites will be filtered more accurately now!
