Frequently Asked Questions
Why is my ad blocker not detected?
Some modern ad blockers are designed to be undetectable as a privacy feature. This is actually beneficial because it prevents websites from detecting and circumventing your ad blocker. If your ad blocker appears to be working (you don't see ads), it's functioning correctly even if this tool doesn't detect it.
Which ad blocker should I use?
uBlock Origin is widely recommended by privacy experts for being efficient, open-source, and highly configurable. Other good options include AdGuard, Privacy Badger (focuses on trackers), and built-in blockers in browsers like Brave. Avoid ad blockers from unknown sources as they may compromise your privacy.
Can ad blockers protect against malware?
Yes, ad blockers can prevent malvertising (malicious advertisements) from loading. Many ad blockers also block known malicious domains and tracking scripts. However, they should be used as part of a comprehensive security approach including antivirus software and safe browsing practices.
Why do some sites ask me to disable my ad blocker?
Many websites rely on advertising revenue to support their content. When you use an ad blocker, they lose this revenue. Some sites use detection scripts to identify ad blockers and request whitelisting. The decision to whitelist is personal - consider supporting sites you value while protecting your privacy on others.
What's the difference between ad blocking and tracker blocking?
Ad blocking focuses on preventing advertisements from displaying, while tracker blocking prevents scripts and cookies that monitor your browsing behavior across websites. Many modern tools do both. Tracker blocking is more focused on privacy, while ad blocking improves both privacy and page loading speed.
