I do that too Keef, but thinking about taking it to the next level one could run a local lightweight http server (say Nginx) and using a host file point all that *.viglink.com malarky to it. The local http server can extract the target URL and redirect the browser to it.
If I knew how to do link filtering in FF I'd write a JavaScript plugin which would be even simpler. I'm surprised Ghostery doesn't already do this for us.
