Thank you for your welcome and advice on ways to contribute to Blokada.
I still need to add details about myself to my profile, to help engender trust and to summarize briefly my experience with software and technology, as well as indicate my experience with, and importance of, GNU/Linux and free/libre software.
I have used Debian GNU/Linux as my primary platform for almost two decades, and currently run it on my laptop and tower, but have no plans to try installing it on my Android phone.
I do, by the way, have experience using DNS over HTTPS (DoH) and DNS over TLS (DoT) on Debian, and have been exploring the predominant (most mature) options for the latter. I have been using NLnet Labs’s validating, recursive, caching DNS resolver, Unbound – although, with Debian stable, deciding on whether to run the included version of a given package is always an important feature, to avoid “breaking” the security and stability of Debian.
I have written documentation for software, operating systems, and hardware. I also have experience beta-testing software, technical support, and QA. I started hand-coding HTML in the early 1990s and had the privately of contributing to the Web sites of organizations such as the United States Holocaust Memorial Museum (where I was contract webmaster in 1996), USHMM.org, and the International Education and Resource Network, iEARN.org.
I do hope, @Karol, that I can, indeed, help Blokada. (I admit that I have not yet tried the beta release of Blokada 5, simply because I understand there are stability issues I realize I must consider.)
