Removes all sorts of un-necessary junk for the URL so that you can easily copy the URL for sharing. Removes things like: utm_source=, etc.
Minimal Status Bar:
https://github.com/crizzo/Minimal-Status-Bar
"This is an extension to provide a minimal (Google Chrome-like) status bar for Safari. It also has built-in longurl support to convert those pesky and opaque short urls to long ones again."
