BROWSERS TREAT BIG SITES DIFFERENTLY

Summary from the TLDR newsletter

Safari and Firefox change how some sites are rendered based on the domain. Sites like TikTok, Netflix, and Instagram get special treatment. This happens because these browsers are playing catch-up when it comes to Chrome feature updates, and this means using quirks and workarounds until they reach feature parity. The resulting loop keeps Chrome dominant as users switch to Chrome for a better experience.
