So almost every GDPR cookie consent banner out there has a section for “legitimate interest” cookies that they can leave on by default and you will inadvertently accept even if you choose “Reject all” unless you go to the detailed settings and disabled those too.
Some of them have dozens of legitimate-interest cookies.
I read some articles about what they are and why it is allowed to keep them on by default, but they were very vague. So can someone explain it to me like I am five?
I set my browser to clear out all cookies for websites unless I’ve whitelisted the website. The whitelist is a very short list of sites I visit that I actually want it to remember that I’ve logged in.
I have all 3rd party cookies blocked.
Someone before me answered the question quite well. No need to repeat it.
