A lot happens when you browse the internet. Ostensibly you’re just looking at nytimes.com, but behind the scenes the page has loaded over 30 external scripts. Most are there to provide you with a more relevant experience — by which I mean, targeted ads.
The good news is that you can install a browser extension to block undesirable content. The bad news is that Google is onto this, and has proposed changes to its web browser that will limit your future ability to use those ad blockers.
