Typically the biggest discrepancy comes from the fact that usage is head-heavy with 1/3rd of page loads being from the top 100 origins <https://twitter.com/RickByers/status/1195342331588706306>, and I would absolutely expect the head to not be using quirks mode. Perhaps there's one or two popular sites using quirks mode? No, only http/https schemes contribute to UseCounters IIRC so about:blank shouldn't be the problem. Or maybe there's some discrepancy in how we're identifying quirky pages. cheers, > -- > Simon Pieters > https://www.mozilla.com/ > -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
