The jumping and delay is from the traffic being routed to the 3rd party. Yes when you click the link you are actually sent somewhere else. Then the 3rd party has to assess whether the link can have the new code attached, adds it or not, then sends you to where you thought you were going in the first place.

The console thing is ljs console (which they keep mightily hidden) but when you are logged in it's for your account. You can't screw up anything unless you randomly start tying stuff in, and then most like it will return a fail condition, meaning nothing has changed.

There's still some debate as to whether this fix applies only to the browser you've done it in though.

And there has been outrage on this twice, yet they continue to do it.
