Jun 10, 2025 at 9:22 PM Mozilla to end Firefox Orbit AI assistant and Deepfake Detector add-ons
Mozilla has announced it will discontinue the Orbit AI assistant and Deep Fake Detector add-ons for Mozilla Firefox, with both tools set to shut down on June 26, 2025. This move comes just weeks after news of Pocket and Fakespot closures, and highlights Mozilla’s ongoing shift away from experimental AI and supplementary browser services.
Orbit, which had been in beta for over six months, offered Firefox users an on-page AI assistant accessible via a floating orb, toggle button, or toolbar icon. It enabled users to summarize webpages or videos, ask questions about the content, and interact directly with displayed information. Notably, Orbit’s design prioritized privacy by processing all user prompts through Mistral 7B hosted on Mozilla's Google Cloud Platform instance, ensuring that data was not shared externally for any machine learning purposes.
Deepfake Detector, also ending on June 26, 2025, was developed to identify whether a block of text was written by a human or generated by artificial intelligence. It used Mozilla’s proprietary ApolloDFT engine alongside open-source models like ZipPy, labeling texts accordingly. The shutdown notice for Deepfake Detector confirms it will become unusable after the end date and thanks users for their support.

This is really how I find out that Fakespot is being shut down. Damn. I remember when Fakespot announced that it was acquired by Mozilla. A real shame, the lot.
