What I would like instead is a browser that treats tabs more like virtual machines that you can roll back, suspend to disk and resume. Little package of data that get frozen in time and are externally searchable.
Maybe look at ArchiveBox. IIRC it has pretty much everything you ask for including an import from your browser history and bookmarks.
If every country did as great as the UK per capita we would be completely and irrevocably fucked.
