Hello westfrs! There are numerous services on the internet that host movies. But for most of them, you have to pay. There are also movies that are less known and likely not blockbusters, but they are free. But I am assuming you are looking for movies that you would watch in the cinema or on TV. Those are not free and me telling you how to watch them for free would be piracy. And anyway, this is Mozilla Support and we are not here to tell you how to pirate movies. Thank you for your understanding, and if I could help, please mark this post as solved.
