Can i stay within the browser when playing Youtube videos in mobile view?

Can Firefox android be set to play Youtube videos when in mobile view, to stay within the browser, and not open the Youtube app to playback the video. Is there a setting, or a browser modifier command? I'd prefer not to have a secondary application open everytime to play videos, but i know in desktop view this is not a problem, (well done Mozilla for continuing Flash playback in desktop view in the latest Firfox version) Thanks
