Not yet.  It's been present in development builds of Gecko 1.9 for a 
while, but not in anything shipped.

I suspect we'll just remove it in favor of the new setup, but wanted to 
make sure I knew what our options are.

I don't really have good data on this.  I suspect the answers are "just 
chrome/extensions" and "not very widespread", but that's just a gut 
feeling, combined with the fact that it's not shipped and not yet 
clearly documented.
