I'm really excited about the privacy enhancements of SRWare Iron over the Google Chrome. You have done a great job, no doubt
Still, there is still only one missing, which in my opinion is very important to the privacy provided by the browser: an option that allows you to block any external extension installing from third party apps. For example, some installation packages, besides installing the application for which were build for, SILENTLY installs Chromium based extensions which can drop an eye/spy the passwords that you enter, sites that you visit and so on. You may not be aware that you have installed such an bad purpose extension and so your privacy will be compromised.
What do you say ?
