I made this extension: https://github.com/fiatjaf/nostr-web-archiver/releases/tag/whatever, which is heavily modified from that other one.
Damn, this "Lit" framework for making webgarbage is truly horrible, and this codebase is a mess worse than mine, but I'm glad they have the dirty parts of actually archiving the pages working pretty well.
Then there is for browsing archives from others.
Please someone test this. If I have to test it again myself I'll cry. I must wait some days now to see if Google approves this extension on their store, meanwhile you can install it manually from the link above.
