most of the times when I surf on YouTube I switch it to desktop version for some reasons but I can't find any options to change screen resolution the definition or quality. it's fixed in 360p. Meanwhile on the other browsers I could easily find changing screen resolution icon like we used to do on the desktop web page. why hasn't Firefox Android browser supported this feature yet???? why don't you update and add this feature in the next version ASAP please. I upload two photos to compare with please check them
