Why has nobody made a browser which adblocks without the website detecting it?

I can got to cnn.com and at first NoScript will only show the option to allow cnn.com, but once that's done you will see that cnn.com wants to run scripts from over 25 other domains!

Check out https://dailymail.co.uk for one of the worst offenders. With MS Edge and its default settings, with no additional ad-blockers, the front page loads almost 260 resources, about 10.5M and it took 1 minute to load the complete page. The dev tools console reports 169 issues (errors, including blocked resources).

Not so if you aren't actually hashing anything but rather are just generating pseudorandom numbers and giving it to them.

Some ad companies let the client supply their own code, but don't actually check it's not crap.

and then you get this: https://en.wikipedia.org/wiki/Malvertising

a good reason to block ads

Yes the Daily Mail is the horrible website. It is actually a trash paper but is worth reading because they are the best paper which is both (a) free online and (b) regularly gets the real dirt behind stories (which the BBC would never host because of PC issues). The DM started detecting adblock only quite recently.

But all the major "dirt" papers are the same server behaviour e.g. The Sun.

I really dislike this trend. There are very few things on the modern internet that I find superior to the old days when sites loaded quickly on even a dialup connection. Most of the modern bloat just gets in the way of accessing the information.

You're right that all of this advertising and scripting is bad, but you need to remove your rose tinted spectacles. The Internet used to be very crappy. Most sites didn't comply with web standards and would only display properly on either Netscape, or Internet Explorer. Insecure Macromedia Flash was widespread and it got worse when IE won the browser war, with its blatant disregard for security and ActiveX nastiness. It was a dream for anyone wanting to gain access to everything on your computer. Winblow$ 95 had no security, with everything running as administrator. Scammers made loads of money with rogue diallers on dodgy porn sites. Eventually IE lost the second browser war, probably due to smart phones, just as much as superior alternatives, sites became standard compliant and we're now where we are, which isn't perfect, but better than the bad old days.
