Hey guys! so, for background, I'm using Firefox Beta on a Galaxy tab. I have this thing when I use the browser in Multi Window and try to highlight a text by tap holding it. the pop-up menu (where you have options such as copy/cut and select, etc.) doesn't really show. this only happens to me on Firefox. what's up with that? also, tapping a word twice doesn't select it even when I'm not using Multi Window... what's up with that?
