My main browser is Librewolf but I keep a chromium browser just in case. Previously used brave but their flatpak is shit. Ungoogled chromium seems ok but it looks like they don’t change much from upstream chromium. Any good chromium browsers which harden their browsers like librewolf does for more privacy?
I dont think Mozilla sends your account data to Google. And because the main homepage uses tracking, that is not a sign that the internal account database is shared. These are completely unrelated.
