How to Block Ads in Your Browser (All Options 2026)
Why Block Ads
Ads aren’t just annoying — many are malware vectors (malvertising), track your behavior, and significantly slow down pages. Some tests show that blocking ads can reduce page load time by 30-70% on ad-heavy sites.
uBlock Origin: The Best Solution for Desktop Browsers
uBlock Origin (free, open source extension) is the most recommended option by security experts. Available for Chrome, Firefox, and Edge.

- Install uBlock Origin from your browser’s official store
- Enable it — blocks ads, trackers, and malicious domains by default
- Advanced mode (optional): enable advanced mode for granular per-domain control
Native Browser Blocking (No Extension)
- Brave: blocks ads and trackers by default without extension. Most aggressive native blocking
- Firefox Enhanced Tracking Protection: Settings → Privacy & Security → Enhanced Tracking Protection → Strict
- Edge: Settings → Privacy → Balanced or Strict
DNS-Level Blocking: Protection for the Whole Home
- Pi-hole: free software installed on a Raspberry Pi or always-on PC. Acts as DNS server on your network and blocks advertising domains. Removes ads even in mobile apps
- NextDNS: online service (free up to 300,000 queries/month) — configure your router’s DNS to NextDNS and block ads on the whole network
Blocking Ads on Mobile
- Firefox Mobile + uBlock Origin: Firefox for Android allows installing extensions including uBlock Origin. Best option for mobile browser blocking
- Brave Mobile: native blocking without extension, available on iOS and Android
- Private DNS (Android): Settings → Network → Private DNS → Enter dns.adguard.com for basic blocking across the mobile network
Is blocking ads illegal?
No, it’s completely legal. Ads are unsolicited advertising and users have the right to filter content they receive on their devices.
Should I whitelist sites I like?
If you want to support a site you value, whitelisting it is a supportive gesture. Most blockers have a button to disable on the current site.
Are uBlock Origin and AdBlock Plus the same?
No. uBlock Origin is open source, has no ‘acceptable ads’ business model, and uses fewer resources. AdBlock Plus has an ‘Acceptable Ads’ program where advertisers pay to have their ads not blocked.
Conclusion
For desktop: install uBlock Origin in your browser. For the whole home: configure NextDNS on the router (5 minutes, free up to the limit). For mobile: use Brave or Firefox with uBlock Origin on Android.
