Troubleshooting ProBlocker (Manifest V3)

Ads still showing?

Run this checklist:

  1. Confirm ProBlocker is ON: Open the toolbar icon and verify the main toggle.
  2. Refresh rules: Settings > Filters > "Update All".
  3. Remove conflicts: Disable other ad blockers. Multiple blockers can fight over declarativeNetRequest.
  4. Reinstall clean: Remove ProBlocker, restart the browser, then install again.
