I'm not quite sure if this is a Google flights problem or Firefox mobile problem, but I'm trying to copy a share link on a saved itinerary from Google flights with great difficulty. When I long press on the link text, the keyboard pops up as do the editing buttons when highlighting text, but the editing buttons immediately disappear, leaving the keyboard behind on the read only text box. Attempting this again gives the same result.

I'm using Firefox mobile 36.0.2 on an HTC one M8, running android 4.4.2.
