I have no idea why you’re completely annihilated in downvotes. You’re right, at least about the incognito mode. I clearly remember chrome introducing this with a blog post or something; my boss at the time even joked that they used an example of “secretly buying a gift for someone” instead of all the dirty, dirty porn you want to watch.

Tabbed browsing, no idea though.

No one is claiming chrome invented the concept of incognito mode. It was just executed incredibly well.
