Unfortunately it doesn't seem to make any difference (at least to the highlight popup, which what I wanted to get rid of) and looks like it has been abandoned. No doubt Medium changed their site (either deliberately to defeat extensions like this, or maybe that was a "happy accident" for them).

It was good while it lasted but the module doesn't work anyone, and development seems to have stopped. Unfortunately Medium is unreadable yet again.

Great work, Matt!
