IsThisSpam - Scam & Spam Detector by Ultron Developments

IsThisSpam adds scam and phishing checks to Firefox. It can analyse messages in Gmail, Outlook and Yahoo, scan selected page content on request, check website risk automatically while browsing protection is enabled, and keep a local report history.

Automatic browsing protection sends the current HTTP(S) URL to IsThisSpam's website-check API. Email or page content is sent only when the user starts a content scan or enables an automatic content-analysis feature. Optional third-party AI providers are contacted only when selected in Settings.

The results are risk assessments and should not replace independent verification, financial advice or legal advice.
