The plugin is broken on https websites. It loads many external suspicious looking scripts over http, like from: http://map.media6degrees.com/orbserv
The result is that in IE and Chrome and other browsers it will give a severe warning that it is loading resources that are not secure.
And this code is obfuscated - to looks suspicious and also is hard to remove. It may have code to one day steal passwords and install spywhere - and how am I to know it wouldn't if it doesn't have plain readable code.
