As a non-Chrome user I'm not your target audience anyway - but if you were doing it for Firefox (or if I were a Chrome user), it would take a lot of very positive endorsements to get me interested enough to really try it out. Until then I'll settle with the fact that browser history will very rarely be the best way to find something I've seen before - most of the time I will have bookmarked what I later want to re-read, so it's not a huge issue anyway.
