I am not the author. I was just so tired of having to manually strip crap like "?utm_term=.b1e20fe33a88" from the end of URLs before sharing them. This extension solves that problem nicely.
I wonder why Google doesn't build something into Chrome that just hides this crap from the visible URL? I guess they could get some PR pushback from paranoids if they did that though. Better to just hide behind some fictitious UTM Inc.
