Feature request: seamless browsing between devices = real-time tab sync

I dream about sync of tabs between devices. Real-time tab sync, not just list of opened tabs on other devices.
During the day I open tabs on my laptop, then I would continue reading these tabs on my mobile later, I would close some of these, keep others and open new tabs also. Keep these changes synced to other devices. Like a task list, but tabs are my tasks.
How could that be solved?
