I am aware that native casting exists in FF (and would have enabled it IF ONLY ABOUT:CONFIG STILL EXISTED). Are there any plans to enable it (e.g. via a setting) or is there an extension to achieve it? Either that or PLEASE bring back about:config. Google Home is a trainwreck but VLC casts flawlessly. Thanks.

I am trying to enable GPC on my phone as I have been having problems for a long time. When I type it into the address bar, nothing happens.So unable to choose the preference I require. Thank you
