Sorry I mean "basic HTML" GMail interface. "Standard" is the bad one with "Chat/Spell checker/Keyboard shortcuts/Adding or importing contacts/Custom from addresses/Rich formatting", none of which I want or need. I hit F12 then Memory then Take Snapshot, the basic iface apparently uses around 1.3MB to show first 100 messages of Inbox. I forgot to mention JS is utterly blocked and basic HTML still works, always appreciated... even if it's Google. Too bad they're also reading all the receipts and populating https://myaccount.google.com/purchases with things I bought from anyone I gave the address to, and never told me about it, or showed me where the kill switch was, if there even was one.
