I personally now use two browsers for different reasons:
* Chrome = Gmail, Drive, Docs, Search that I wanted tracked (work related usually)
* Chrome Incognito = Social media (Twitter, Instagram) and sites I stay on most of the time (HN)
* Firefox Private Browsing = Search that I do not want tracked (shopping research usually), shopping, news sites, media sites, LinkedIn
One can also view these in terms of cookie/data retention periods:
* Chrome = +1 week
* Chrome Incognito = 1 day maximum
* Firefox Private Browsing = Session (created and destroyed for a specific purpose, short-lived)
And yes, it's not convenient as if I get an email with a link in it I will copy the link into the appropriate browser and then browse to it. But then the upside is that I don't get tracked relentless by tracking stuff that expects cookies.
Oh, and I'm aware of IP tracking too. I tend to use PIA VPN for this reason and do not autoconnect to the closest place, but instead semi-randomly pick somewhere in Europe to surface from each day.
