In Firefox's "couldn't establish a connection" page, the cute Mozilla is having trouble connecting two cables together. The stress lines imply that he's pulling but can't get them to meet.
But the cables both have visible slack in them. The image implies not that the connection CAN'T be made, but that Mozilla doesn't WANT to.
This bugs me. https://elekk.xyz/media/MecB2KDeh83SDPbxlPQ
