Has anyone used these browser button tools.  I had them on my PC but I can't find them now to install on my mac.  You would click on a button and a smaller window would open up.  In the field you would type either english or japanese and then a new window would open with a list of related matches.  This was a very quick and useful tool.

If anyone knows where I can find these or a similar tool for my browser please post a response.  Thanks in advance.
