Lesson 5 of 5

Common ad-blocker myths

Speed, security and ethics, cleared up.

4 min read

Ad blockers do not slow your browser; they speed it up, because there is less to download and render. They do not break most websites; only sites that depend on ad scripts for layout.

Blocking ads is legal in every major jurisdiction. Many users block ads for security reasons: malvertising is one of the most common malware delivery channels on the open web.

Key takeaways

  • Blockers reduce CPU and bandwidth usage on average.
  • Blocking ads is legal and explicitly protected by browser APIs.
  • Blocking trackers improves security as much as privacy.
