"While future IoT devices are a privacy (and security) nightmare, we can take simple steps to leave a smaller digital footprint when using the web: use private browser windows more often, use a separate web browser for Google and Facebook services, use a separate browser with privacy tools for the rest of your web browsing." What I really want is a chroot jail for a browser. This shouldn't be that hard, but the GUI adds some complexity ... and I am not sure how to implement it in OSX. I can do this immediately with vmware fusion, but that's a lot of overhead - quite expensive - for just a second browser instance. It gets even more expensive if I want a third or a fourth.
