Hello Darkion.
My recommendation will always be to divide your internet activity into several browsers. For my part I recommend the BLT pack (Brave, LibreWolf & Tor), and if you want to use one more maybe I would use an Iridium Browser or a Vivaldi configured to measure, but as I say, it would be something optional.
I know that some of the proposals cannot be fully audited, but hey, I feel confident in them, and a bad one I can always do without those who fail me.
In addition, it does not matter which browser you choose if you do not take more measures, such as using certain search engines and extensions, using VPNs and alternative DNS resolvers, avoiding certain websites and adopting certain attitudes and habits...
I hope I have helped you a little. Greetings.
