SRWare Iron has an interface similar to Google Chrome. The problem with Google Chrome is that Google monitors how a person is using the program.
Depending on the configuration, each time you put something in the address line,this information is sent to Google to provide suggestions. If you have typed a false address in the address bar, this is sent to Google and you get an error message from Google's servers.
These are included so as to improve the Google search engine. But it can be a problem regarding privacy. SRWare Iron doesn't give out any such personal information.
