What it is
An ad blocker is a small add-on for your browser that stops most ads and trackers before they load. Result: cleaner pages, fewer pop-ups, faster browsing.
Why people use it
-
Less noise: read the page, not the banners.
-
More speed: fewer scripts = faster loads.
-
More privacy: tracking pixels get cut off.
How it works (30-second version)
-
Uses filter lists to spot ad/track domains.
-
Blocks those network requests on the fly.
-
Lets you allowlist sites you trust.
Heads-up
-
Some pages ask you to “turn it off.”
-
Rarely, page features can break.
-
You can allow ads or use paid support to help creators.
Get started (1 minute)
-
Install a well-known blocker for your browser.
-
Keep it updated (lists refresh automatically).
-
Allowlist sites you want to support.
What an ad blocker cannot do
An ad blocker does not scan downloads, patch browser vulnerabilities, or prove that a page is safe. Ads served from the same domain as page content may also bypass a filter. Treat it as one layer against tracking and malvertising, not as antivirus protection.
Choose and configure one safely
- Install a well-established extension from the browser's official store and verify its publisher.
- Review requested permissions and avoid extensions that need unrelated access.
- Use one primary blocker; overlapping extensions can break pages and make troubleshooting difficult.
- Allowlist a site only when you trust it, and review that list periodically.
- Keep the browser and extension updated, and remove tools that are abandoned or sold to an unknown publisher.
