I really dislike the cookie disclosure popups that appear on websites. Ideally I shouldn’t be seeing them at all — I know that the EU requires it, but I’m not a citizen of the EU so the regulation should not apply to me. But I’m pragmatic enough to know that not every web developer can or will selectively show this disclosure popup based on the geographic region of the visitor.

That’s why I’m wondering if these disclosure popups would be better handled by the browser.

The way I see this working is that when a website tries to set a cookie, either through a response header or within JavaScript, and the user is located in a jurisdiction that requires them to be aware of this, the browser would be responsible for telling them. They could show it as a permission request popup, much like the ones you see already when the site wants to use your microphone or get your location. The user can then choose to “accept”, in which case the cookie would be saved; or they can choose to “deny”, in which case the cookie would be silently dropped or an error will be returned.

This has some major advantages over the system we have now:

  • It would save the website dev from building the disclosure popup themselves. I’ve seen some real creative ways in which websites show this disclosure, but honestly it would just be simpler not to do it. It would also cover those web developers that forget (or “forget”) to disclose the presence of cookies when they need to.
  • The website does not need to know where the user is browsing from. Privacy issues aside, it’s just a hassle to lookup the jurisdiction of the originator based on their IP address. Which is probably why no-one does it, and why even non-EU citizens see these disclosure popups. This is not a problem for the browser, which I’d imagine would have the necessary OS privileges to get the users’ current location. This would be especially true for browsers bundled with the OS like Safari and Edge.
  • When the user chooses an option, their choice can be remembered. The irony of this whole thing is that I rarely see websites use cookies to save the my preferences for allowing cookies. These sites seem to just show the popup again the next time I visit. Of course for a user chooses to deny the use of cookies, it wouldn’t be possible for the site to use cookies to record this fact. If the browser is managing this preference, it can be saved alongside all the other site permissions like microphone access, thereby sitting outside what the site can make use of.
  • Most important of all to me: those outside the jurisdiction don’t even need to see the disclosure popup. Websites that I visit could simply save cookies as they have been for 25 years now. This can be an option in the browser, so that users that prefer to see the disclosure prompt can do so. This option could come in handy for those EU citizens that prefer to just allow (or deny) cookies across the board, so they don’t have to see the disclosure popup either (I don’t know if this is possible in the regulation).

Of course the actual details of this would need to be ironed out, like how a website would know whether the user has denied cookie storage. That’s something for standards committee to work out. But it seems to me that this feature is a no-brainer.
