Misleading name, far from stealthy. Rated 4 out of 5 stars
"Stealthy" is everything but. In my tests it used transparent proxies that readily reported ones real IP to anyone who was asking. This is NOT a "stealth browsing" add-on, one is at no point anonymous to the sites visited.
This add-on does succeed in circumventing some of the less aggressive region restrictions, but far from all of them.
It's a simple to use add-on that requires some trust and it has its merits. However, I don't feel like the tool is fully and properly what it does and doesn't do and how it does it.
