Safari content blocker rule limit

AdGuard for Safari uses the Content Blocking API to apply filtering rules to pages in the Safari browser. Currently, a maximum of 150,000 rules are allowed for each content-blocking extension.

AdGuard for Safari has 6 content blockers:

  • AdGuard General
  • AdGuard Privacy
  • AdGuard Social
  • AdGuard Security
  • AdGuard Other
  • AdGuard Custom

This makes a total of 900,000 filtering rules.

However, an extension can contain up to 150,000 rules. If you exceed this limit, some of the rules will not be applied. This may lead to incorrect blocking.

How to check if you are exceeding the rule limit

  1. Open AdGuard for Safari app.
  2. Scroll down and click Content blockers.
  3. Below each content blocker, you can see the enabled filters and the number of active rules. Content blockers

If more than 150,000 rules are enabled in a content blocker, you may need to disable some filters or user rules from it. Go to Filters, select the problematic category, and disable the filters or user rules you don’t need.
