Instead... right click on the blue bird in the image and choose "Open Link in New Tab"
Why doesn't the link work? I don't know.
YET another way is to hover over the picture just to the right of 'spreaker' in this tweet - the RED X (obviously, it would be something else in another) and 'click' there and it too opens up in a browser.
HOWEVER... IF you want to post it on Facebook, DO copy and paste the link provided to FB.
