Interestingly enough, Ozone's author(s) is mysteriously elusive. It is a really good browser, so I would conclude that it took a lot of money to develop. Why is there no mention of a company or author? With nobody to give credit to, there's nobody to take blame -- for better or worse. It's hard for me to trust my identity (gmail username/password, for example) to Ozone. For all I know, there's a good chance Ozone is the fruit of an organized crime effort. I'm pretty sure someone could earn a buck or two if they full access to the kinds of information people, usually trustingly, put into their web browser.
So while I'll be using Ozone for everything I can, I won't be giving it any information I wouldn't openly post on the internet.
