Upcoming User-Agent Reduction in all Chromium based browsers

Support & Bugs
1

Hello,

Google announced that it will stop supporting User Agent header in original scope. This means the info we used to consume to detect device/OS/browsers will be significantly limited in User Agent.

Google is trying to enforce migration to User-Agent Client Hints. Now important questions:

  1. Is Matomo team/product ready for this?
  2. Is Matomo ready for User-Agent Client Hints?

Usin paid cloud version.

I’m really shocked that no Matomo representative has answered above questions.

30 days passed, Matomo come on!

Hi @nagyalex
As you use the cloud version, you can ask by mail to the support team…

According reply from support:

It looks like this change has already been rolled out according to this guide: https://developers.google.com/privacy-sandbox/protections/user-agent

Matomo already looks for client/browser hints: https://github.com/matomo-org/device-detector/blob/c9952fc4d31dd249d2bf7dc88ca9963c7a2739b7/Parser/Client/Hints/BrowserHints.php

This change shouldn’t affect much unless a visitor uses a browser that doesn’t support client hints.

Cloud Matomo uses https://github.com/matomo-org/device-detector/tree/master

The Universal Device Detection library will parse any User Agent and detect the browser, operating system, device used (desktop, tablet, mobile, tv, cars, console, etc.), brand and model.
