Terrible, doesn't work! Keeps saying, "failed to shorten", and then demands that I acquire an "T.LY API key" because I've hit an extension limit. I'm not using T.LY and it doesn't matter which other URL shortening service I use, it keeps saying that. Then it keeps popping tabs open in my browser to the T.LY website demanding that I register with them. I'm not even using their service. MESSAGE TO DEVELOPER: fix this, or at least get rid of T.LY service altogether.
