This is a follow up to my earlier post on this topic: Mesh link all tabs in Safari window.
I’ve created a Launchbar action using the below script to mesh hook all tabs in a Safari window. (Launchbar is an Alfred-like app, and the script can almost certainly be fired by an Alfred action, also).
You can download the action here. To install: After downloading, delete the .zip extension; then double click the .lbaction file and it should become one of your LB actions.
