There are also other methods like a beta extension called fx_cast on Firefox PC but we wouldn’t recommend them owing to their buggy nature and their terms of agreement. Last but not least, if you don’t feel the above methods are worth your time, you can always use Google Chrome which has a simple cast option in the settings. And if you’re using an Android phone then you can simply cast the screen of your phone from settings.
