I had it as my main browser for a while. It is very basic but was quite stable and didn't tend to slow down or crash. Thing that really irritaed me was that it couldnt save any data or log in details so always had to spend ages logging in to every website.
It'd be better if you provided a link to what you talk about. I had to search on Google (not that much work, but anyways) just to discover (if I got the right result, and you're not talking about something else) it's for Apple's Mac.
Sorry but I like penguins better. Specially those named "tux"! 😀
About the concept of that browser, I like it, it's something that should come by default on Firefox and Chrome, but on both browsers you can achieve that by using the Private/Anonymous browser mode. There's also certainly an extension/plugin to do that on both browsers. If there isn't... quite strange, no? (specially on Firefox, it has much more plugins available than Chrome for now)
