NoScript helps with this sort of thing. And of course uBlock Origin, Privacy Badger, DDG Privacy Essentials, and HTTPS Everywhere. I sort of feel like I shouldn't have to wear a suit of armour just to go out and buy some milk, though...
Note: Domains I'm blocking scripts from on this page alone include admedo.com, doubleclick.net, and google-analytics.com – physic, heal thyself!
