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?
didn’t you read my comment? That whole post is marketing excuses for not being free software.
Try compiling the “source code” they release and tell me if you get a usable version of Vivaldi.
