The term Stealthy refers to military aircraft that can penetrate into enemy territory undetected by radar. In a way, that’s what this browser extension does.
Some organizations and governments block access to web pages, and certain online services are not available in all countries. With Stealthy, users can make themselves undetectable, and thereby able to bypass the censorship.
This can be tremendously important in countries like China or Iran, where regimes censor the Internet. But even in countries like Germany, many people cannot watch music videos on YouTube because of a licensing dispute with GEMA. With Stealthy installed, this is not an issue, as you can get a foreign IP address and play the videos without issue.
Once installed, a small stealth aircraft icon will appear in your navigation bar. The color is red by default, indicating Stealthy is off. After clicking on it, Stealthy automatically searches for an appropriate proxy, sets up your browser, and turns the icon green, meaning you are now in Stealth mode.
