I must have missed the HN discussion when Mozilla announced they plan to sell [ads based on] browsing history... I'm not sure how that fits in with putting privacy first.

My understanding of how the ads work is that the browser downloads a list of ads tagged by category, and chooses one to display based on browsing history that never leaves your computer.
