Pinnes tabs solve that, actually. Whenever I hit a Facebook link or whatever it just switches to and navigates the Facebook tab to the URL. This is an awesome feature and probably singelhandedly responsible for cutting my tab count by the tens anyway. Still not enough, but definitely a step in the right direction.
Do you mean pinned tabs? It doesn't switch to the existing tab for me on chrome with osx. In what environment does this work because I'm very interested in it.
Oh sorry, I meant in Safari. Pinned tabs in Chrome was the killer feature that kept me around. When Safari finally got them I switched in a heart beat and haven't looked back since. (Other than for dev.)
