Best way to stay anonymous on chrome?

Firstly, you're not going to be completely anonymous if you are windows.
Chrome probably isn't the best.
I would recommend that you use Brave (Unless you are okay with using TOR or an alternative) + a VPN that doesn't disclose records. (Hard to find one that will actually not sell you out.)

If anonymity is your first and foremost priority i would heavily recommend you check out a different OS. I used to use Tails but I'm sure there are a few alternatives to that as well.

You can do that all in a virtual machine. It's what I do to run sock accounts perfectly.

Stay safe out there. :sip:
