Two of my favorite Safari Extensions

There are always the first extensions I install on a new Mac, or if I do a clean install on one of my older machines. As of writing this, they both still work without any issues.

Clean URLs:
https://alexander.kirk.at/2011/03/30/safari-extension-clean-urls/

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."
