Sources and verification
- Shutdown
- This is the confirmed service-end day, not a date inferred from a passed deadline. A June 9, 2025 approved help-page revision records the announcement month; the first public announcement day and cutoff time zone remain unknown. Firefox, its separate AI sidebar and Mistral models are outside scope. The retired product site redirects to a different Mozilla announcement, and the extension listing returns 404; neither redirect nor 404 is the closure evidence. Official shutdown notice

- Launch
- Mozilla introduced the available beta on September 23, 2024. An archived official homepage was already public on September 18; the exact first availability day is unverified, so the record retains month precision.
