Cache partitioning isolates the caches of distinct domains.

    this makes too much sense:

    isolates the cache belonging to website A from the cache belonging to website B. The isolation ensures that B can’t query for cached content of A to see whether the user visited website A before

    also wondering if the temporary containers mitigates this, except perhaps in tabs opened in the same container (which may happen frequently when using one pinned search tab)

      Yes, apparently containers do isolate what network partitioning will now isolate on a first-party domain basis (wiki)

      Yeah, it really seems like one of those ideas from the early internet where malicious sites were few and far between.
      And then it presumably stayed for so long, because performance was the only metric that the broad masses cared for. Glad to see that slowly changing.
