There have been many articles and conversations about the question of how to get the URL of a Google search in Safari 6. Some solutions include using the Terminal to get the URL, using AppleScript, using bookmarklets, and using Automator. I created a Safari Extension to make this process easier.
Get URL: Easily get the URL of your current tab.
With my Get URL Safari Extension, simply click the toolbar button for a popup that contains the URL of the current page. The URL is already selected, making it simple to copy.

Update: I’ve received notice from Apple that the extension will be available in the Safari Extensions Gallery. Look for it there soon!
