My friend who works in an adtech company: "Protip: Use Firefox instead of Chrome. We get very little data from Firefox users"
Latest Firefox still doesn't protect against browser fingerprinting. This from the EFF Panopticlick: Your browser fingerprint appears to be unique among the 303,579 tested in the past 45 days. Currently, we estimate that your browser has a fingerprint that conveys at least 18.21 bits of identifying information.
1. Blocking redirect tracking is about more than just fingerprinting users. I'm a huge fan of Panopticlick's work here, but it's not a be-all end-all measure of whether a browser is getting more or less private. There are a lot of different, complicated things we're talking about when we bring up browser privacy.
2. Disable Javascript with something like uMatrix by default, and that number will drop dramatically. By default with JS disabled, I think my Firefox leaks about 8 bits of information, which Panopticlick lists as sufficient protection.
Major caveat in that non-JS users are likely disproportionately represented at Panopticlick, and people shouldn't use Panopticlick as more than an indicator of what's possible. In the real world, disabling Javascript will leak more bits since fewer other users will be doing it.
However, it's still likely worth doing if you can tolerate the inconvenience. And of course, the more people that block JS by default, the better protection it provides.
