> For me, Firefox seems to be making decisions with user's security and privacy in mind, and I see that as a net positive. As a long time user, it is the only reason I use Firefox. I agree that that is a good thing. However, the more firefox breaks compatibility with sites people use, the harder it will be to regain marketshare. And if Firefox keeps losing marketshare it will have less ability to influence web standards, and could potentially die altogether, which would be bad for privacy and security in the long run. Fortunately, state partitioning isn't enabled by default on Firefox yet (it is part of "strict" ETP), so only people who are ok with it potentially breaking sites will turn it on.
