I want to browse the net with only bitmaps being sent to me. I do not want to execute your javascript or markup or make requests other than what i have initiated. Please god someone make a docker container i can spin up on a throwaway computer that renders pages and sends bitmaps of the site to my main computer

Edit: even better, every tab is a separate container instance, i close tab, it nukes the container

To render pages on a throwaway computer and send only bitmaps, connect to the throwaway computer via VNC and run an ordinary browser.

As for improving on tab isolation over what existing browser sandboxes already offer, lightweight virtualization a la Firecracker seems like a more useful increment than containerization, and, assuming each tab has a similar VNC-like connection to its browser VM, virtualization would also make the whole "throwaway computer" setup less necessary to provide a meaningful security improvement.

Sounds a bit like WebRenderingProxy.
