As the name suggests, ad blockers are web browser extensions that broadly block online ads from loading in your browser, including in search results. By blocking ads, would-be victims are not shown any ads at all, making it easier to find and access the websites of legitimate brands. Ad blockers don’t just remove the enormous bloat from websites, like auto-playing video and splashy ads that take up half the page, which make your computer fans run like jet engines. Ad blockers are also good for privacy, because they prevent the tracking code within ads from loading. That means the ad companies, like Google and Facebook, cannot track you as you browse the web, or learn which websites you visit, or infer what things you might be interested in based on your web history. “Of course, you can switch your ad blocker off any time you want, and even allow or deny ads for entire websites,” adds the report.
“Ads are still an important part of what keeps the internet largely free and accessible, including TechCrunch (and Slashdot!), even as subscriptions and paywalls are increasingly becoming the norm.”
