Firefox: Smart Window Beta Mozilla released the beta version of Smart Window for Firefox, an AI assistant that prioritizes user privacy by not storing chat transcripts, using conversations for training, or selling data. The company processes only limited technical information to maintain service reliability. Your chats stay private Unlike most AI assistants, Mozilla doesn’t keep your chat transcripts, use your conversations to train models, or sell your data. To keep Smart Window running reliably, we process limited technical information, like response times and token usage. Your chat content is only shared if you choose to share it.
