Unless you have a firewall or proxy that prevents that particular site 
(via blacklist or whitelist) from doing that.  Or unless you have a 
browser extension that prevents such things.

So shared workers are in fact adding a new vector: browser extensions 
will need to be changed to handle them, and they can't be dealt with at 
all via wirewalls or proxies.
