1Blocker Website Inspector allows you to detect number of ads and trackers on a page, analyze content size and loading time, as well as estimate 1Blocker effect in Safari. See for yourself how many ad networks and analytics providers build deep profiles about you across the web.
Using 1Blocker you can also block these ads and tracking scripts in Safari. In addition to ad blocking, you can also block comments, various social widgets, share buttons, obtrusive EU cookie law notices, custom web fonts, adult sites, and more. Compatibility: OS X 10.11 or later Home Page - https://1blocker.com/
Efficient & Secure Blocking
While most other extensions block content by filtering elements of already downloaded page, 1Blocker uses modern WebKit blocking technology to tell Safari in advance what should be blocked. This vastly improves efficiency and saves battery life. More importantly, 1Blocker doesn't expose your privacy by scanning content of the pages you visit.
Whitelist Safari Extension
1Blocker is highly configurable. It comes with 28,000 preinstalled blockers and lets you whitelist websites you love with a Safari extension. You can also block various social widgets, share buttons, obtrusive EU cookie law notices, custom web fonts, adult sites, and more.
