Worked fine on mine (chrome on Android): touch and hold and wait for pop up. If the link in the upper right is cut short with an ellipsis, touching the link will expand it, just like ellipsis shortened alt texts.

no, but at least here on Fx mobile, i can long-tap and see where it's going.

Depends on the device and software. At least on my phone's Firefox browser a long-press of a link will bring up a menu that includes the URL (though it can run into space constraints for long URLs).

On iOS, that loads the page in a pop-over window.
