DivestOS is the same guy managing the Mull browser. Maybe in future Signal or LibreTube. I tried to donate for Thunderbird but they don’t want money due to required mail and blocking specific mail services. I bought FairEmail and Netguard.

Other possibilities: Tor related services and PersonalDNSFilter

The issue was closed as beging fixed but it isn’t.

So often…

And many do not offer it at all
