It's right at the top but it just gets in the way. I'd like to remove it completely, or send it to the bottom. This also applies to when I long press a link and get the context menu.

I've done some research. I see articles on customising the Firefox menu that only works for the desktop version. I see annoyed users looking for alternatives to an add-on that used to move the option to the bottom before it broke in a Firefox update. I don't see any options for disabling it.
