There's a lot of security research going on at lots of places in all sorts of ways and that's great. But most of it results in better theoretical understanding. It doesn't result in an OS that can be used on commodity hardware in a production context. Good luck running Firefox on top of a some research OS written in Modula 3.

I just gave that as an example to illustrate the point about those security measures. There's others in real OS's and products in production now plus more that existed decades into the past. And quite a few, including one I named, can handle Firefox. Good, wild guess though as untrustworthy browsers designed for untrustworthy UNIXen are hard. ;) Look up OP2 Web Browser or IBOS Illinois Browser Operating System next time if you want architectures designed for secure OS's. Chrome's security was a knockoff of a predecessor of one.
