By track I mean collect information about me, my browsing habits, my interests. By big tech I really mean any company, but mostly the FANG ones. Could you provide some good resources on how to do these public searches? I assume you don’t just mean to look up my full name on Google.
Thank you! uMatrix is a browser extension that makes it very easy to block any third party requests a website makes by category. For example, if example.com loads fonts from Google that is considered a third party request. Or if it tries to set a Facebook cookie. uMatrix shows a table (or a matrix) of all the request addresses and categories and you can click on them to block/allow them.
I don’t think the answer is that simple. I can’t access my computer at the moment to test with the websites you provided, but yesterday I wanted to find out the resolution of my browser and I went to some website that prints it. It didn’t work at first because it used some third party script for that which uMatrix blocked. I wouldn’t be surprised if most websites don’t do a lot of “first party” tracking.
