Limits worth knowing in LeechBlock NG

  • It blocks only inside the browser where it is installed; other browsers and desktop apps are unaffected.
  • The developer says it is not designed for parental control or for blocking offensive content.
  • There is no macOS or iOS version; the site points to ivBlock, a separate product based on LeechBlock.
  • The browser may still connect briefly to a blocked site, so the developer suggests a HOSTS-level blocker when no connection at all is wanted.
