Smart Window (Firefox's optional, privacy-first AI browsing experience) has some updates: New: source-backed answers powered by our Exa.ai partnership, smart tab grouping with one-click duplicate cleanup, and a history view to find pages faster. What remains: no transcripts kept, no training, nothing sold. Memories stay on-device, fully editable. Private Windows untouched. This is still in beta, English in US/Canada, and still fully optional. More here: https://blog.mozilla.org/en/firefox/firefox-smart-window/
