Probably the best and easiest thing I do for my privacy is installing a few browser addons, for me it’s EFF’s privacy badger.
It has no visible effects other than it accidentally blocks a bunch of ads too, so a net improvement over my browsing experience.
uBlock Origin paired with Badger works quite well.
What does Badger add that uBlock with EasyPrivacy and Fanboy’s Anti-Social List doesn’t?
Badger is a good starting point for users and provides an intuitive representation of trackers through the UI. The controls for that (i.e. being able to adjust enable/disable certain things) is more entry user level friendly than say, going through all the source lists on uBlock and understanding what is blocked. I find the controls more granular so one can adjust as desired. I will admit to not having spent sufficient time going through all the lists within uBlock.
In some cases, such as browsers, security can come at the expense of privacy. Every security setting disabling a feature to decrease attack surface can likely be detected from JS, making your browser that much more fingerprint-able.
EFF’s Panopticlick is a good starting point for browser fingerprinting and tracking.
Good point, I didn’t think of that. For that example you mentioned, do you know if there are any extensions that try to fake the feature? I know XPrivacy does something similar on Android.
