Warning to all Brave Browser Users
Blocking variations.brave.com which is used for A/B testing could potentially break Brave’s functionalities. For me did Brave’s “forgetful browsing” feature broke which seems to be disabled by default if you block this domain.
It has included some privacy measures to resist fingerprinting like letterboxing and has more privacy focused search engines as default like searx. Also it takes out some firefox utilities like pocket which I don’t really use
As for Mullwav browser I’m not really sure, it seems to be another reinforced firefox like librewolf
