How to add Samsung tv for casting video

Hi there,

I'm pretty sure you can cast Firefox to a Samsung TV, but it may have to go through your operating system casting tool instead of Firefox native capability because we don't have that.

If Firefox is acting up, I’d try Troubleshoot Mode first since it temporarily disables extensions and some custom settings. If the problem disappears there, you can usually narrow it down to an extension or a browser customization rather than reinstalling everything.
