Anybody figure out how to hide the big orange useless button that's getting in the way of the article text at the bottom of the screen? (on Firefox on Android).

Anybody figure out how to hide the big orange useless button that's getting in the way of the article text at the bottom of the screen? (on Firefox on Android). There's a three dot button next to it but when I press it there's no "close" or "hide" option.
