After reading the article on the Mozilla website explaining how to use the "send to" option for Chromecast on Firefox Android, I cannot seem to find the option. I am on a video with supported format, and the cast option is not showing on the video window or on the URL/address bar. I also noticed that the read-only option is not showing, either, and it usually does. I cannot send video to my Roku either, which has the Firefox channel installed. Is this some update, or is this something I can fix? I've gone through all setting and options and can't find anything. I'd really like to use Firefox to cast video to my Chromecast rather than using Chrome. I'd be pretty disappointed if this feature was removed.
