Honestly I've been using the "I don't care about cookies" extension for several years now, and I can't live without it (same with an ad blocker). I've even switched from Chrome to Kiwi Browser on my Android (it's a Chromium flavor that support extensions), just for that purpose.
Thanks for the tip. Apparently, "I don't care about cookies" has been bought out by the spyware vendor Avast, so people don't trust it anymore. There's now a de-bloated open-source fork "I still don't care about cookies" instead.
