Firefox

Coming soon

We're submitting the Firefox add-on to Mozilla. Watch this page for the install link, or follow the changelog on GitHub.

Safari and other browsers

We don't have a Safari extension yet. Safari requires a separate macOS app wrapper, which adds significant complexity for a small audience. We may build one if there's demand.

On any browser, you can still use the site itself at crazytos.com/analyze to check any TOS.

What the extension does

  • Reads only the URL of the tab you're on, only when you click the icon.
  • Looks up that site's TOS rating from CrazyTOS.
  • Doesn't track your browsing history, doesn't send page contents anywhere unless you explicitly click “Analyze this page”.
  • No accounts. No ads. No third-party trackers.
