I think this is okay as long as there is a compatible protocol. FF was supporting RDP/CDP for a while but recently shifted away in favor of WebDriver BiDi[0], which supports the methods required for dn[1], and now appears at parity support between Chrome and Firefox[2]
I imagine we'll get FF support in the latter half of this year.
It looks like this works by making the browser use dn as a local proxy. That should also work with non-chromium based browser right ? I guess it will then be necessary to configure the proxy manually.
Conceptually yes, but specifically it's implemented by intercepting the browser's internal fetch process. So it's like a "browser-internal" proxy -- or not a proxy at all.
You could do something similar with a proxy, but it may run into issues with HTTPS, which this gets around as we are beyond the terminator. In this way, you can serve the content, and save the content, via getting in the middle of the same fetch process and the browser doesn't know the difference (mostly).
Yes, I want to expand it to that. I imagine with a helper server (or p2p service) that can serve your archive out to people you share it with.
You could even have the index available as well. I imagine like you can create an archive on a topic you're expert on, and then it's like a little subject-matter focused search engine and library for that. :)
