I've used the chrome one but it's not even close to the Firefox extension regarding usability. The tree-style view disappears when you do anything but interacting with it and you must confirm closing a tree which slows things down severely. It works but it's just not integrated as well on Chrome as on Firefox. Thanks for pointing out the Opera one, I'll have a look at it :)
