"textContent": "submitted by XLE to privacy\n55 points | 10 comments\n\nI was reading a review of Firefox’s experimental Smart Window feature, and this stood out as a potential huge issue:\n\n> Smart Window uses ‘memories’, things Mozilla says “…it learns from your activity” to inform its responses.\n>\n> You can delete memories individually, and you can set any given chat session to not use/store them.\n>\n> Fine so far.\n>\n> The problem? My memory list isn’t populated with things Smart Window learned since I enabled it. Oh no.\n>\n> It has activity going back months. We’re talking searches and website interactions from long before I enabled this. features.\n>\n> Firefox just handed that history to the AI models to plough from, without telling me upfront.\n>\n> I found this the creepiest aspect of Smart Window.\n>\n> Mozilla says this was a flub; it will refine the onboarding around Smart Window to limit memory formation to post-opt-in activity only. That’s obviously the right fix.\n>\n> Because sharing a user’s prior browsing history with third-party AI models, silently, on feature activation, without any headset? Yeah, a bit icky – but that’s the price of testing features that are finished, I guess.\n\nThis news leaves me with more questions than answers:\n\n * Was this summarized on enabling this window, or earlier?\n * Did it use an existing model, or re-use one that someone may have already downloaded for a different feature?\n * Is this activity going anywhere else, like Mozilla’s recent “privacy-preserving” advertising?\n * When this releases, what will the default be?\n\n",
