@veshta said in Opt-Out cookie segregation/bundling:

But just for sake of argument, how does your modus operandi distinguish tracking cookies set by 1st party rather than 3rd party?
That "solution" is growing as a way to circumvent the only realistic block option browsers possess - 3rd party block.

My solution works. Block by default and allow only a small number of sites to set cookies. As for blocking tracking, I have subscriptions in uBlock Origin to do that.
