I’ve not had good luck with Firefox on mobile, I use duckduckgo. I’m not forcing anyone to do what I do. YouTube is my main source of media for the most part. I use it on my smarts TV’s in my house - and I haven’t set up computers on all TV’s yet… So it is what it is and it works for me.
Edit: down voting my personal opinion and what I choose to spend my money on for my own convenience isn’t going to change my mind… Just saying
