Thanks for asking! ID Protection is now working with Mozilla Firefox, but currently it's only available through the website version. You can access your full account and all features by logging into the web portal through Firefox. Identity Theft Protection | Trend Micro ID Protection
We're still developing the Firefox extension, so that's coming soon. In the meantime, the website version gives you complete access to all protection features and monitoring.
Let me know if you have any other questions!
Best,
James
