I've been thinking about browser privacy from a different angle: not hiding what you browse, but hiding what's visible on your screen when you share it. Screen sharing during video calls basically bypasses every privacy tool you have running (VPN, tracker blockers, etc.) because the other person sees your raw screen.
The layered privacy defense framing makes sense. This handles the ISP/tracking side. But what handles the "accidentally showed my email to my entire team during a screen share" side? Different threat model but equally common.
Congrats on shipping.
