I also found this one:

I think the general conclusion is that very few browsers don't snoop, and those that don't might not have a lot of features that many users want. At the same time, several features require allowing certain servers to give or receive data, logging in, loading certain addons, etc.
Given that, what to avoid will likely be dependent on what you want and are willing to give up by way of features. In my case, I need to log in various sites to communicate with friend, relatives, and colleagues, buy goods, use services, etc. I'd like to try various new features and have time to do so. In which case, I decided to do the ff.
Firefox with about:config tweaks (but once I experience fewer problems with LibreWolf I might switch to that)
Multi-Account Containers to separate social media platforms, storms, etc., from each other, and then create several non-personal and non-works accounts for sites that don't need them
Cookie AutoDelete or similar to retain only cookies needed for logins
and another browser (Iridium) for a work account.
For anything else, I add the usual, like uBlock Origin or Adguard (which I now use because I availed of the cheap lifetime promo). I might try additional addons and options, but they sometimes break web pages.
That way, I can still maintain some functionality (like reading embedded content from other platforms where logins are required), with more tracking involving non-personal accounts.
