claude can control broser without any plugin/extension using remote debugging port instead

Or just skill for computer use which just clicks on the screen.

chrome exposes when it does this to the website. thats why if you want to scrape websites making it hard you use a forked firefox made for that.

id dont scrape for profit but for hobby projects. and some of websites them are annoying.

It is you that is annoying.

You can detect any debugger attached to any browser running V8 with:

    let cdp = false;
    const orig = Error.prepareStackTrace;
    Error.prepareStackTrace = function () {
      cdp = true;
      return orig;
    };
    console.log(new Error(''));
    // cdp === true  → a debugger/automation client has the Runtime domain enabled

That sounds a lot like United might lose a lot of their most valuable customers.
