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 don’t care about that, you said:
Vivaldi was set as default in Manjaro Linux
And it’s not true.
It was set as default for Cinnamon distribution, which is not even maintained by Manjaro developers, it’s a community managed distribution.
