PrivacyTools Hi BurungHantu, and thank you for your comment.
I'm glad to know that you plan to add LibreWolf in the browsers section. Your proposal, to replace Firefox with LibreWolf, seems completely correct to me, except for a small nuance, and that is that I do not think it is correct to remove Firefox from the section, or at least not completely.
I would think it would be a great idea to replace Firefox with LibreWolf but, within the description of it, include some mention of Firefox and the user.js of Arkenfox.
For example: "While LibreWolf has superior privacy and security protection to Firefox, LibreWolf also sacrifices some useful features against Firefox that not all users would be willing to lose. This is why it can also be an interesting proposal to use Firefox with the user.js of Arkenfox. By including this configuration in Firefox we can obtain a similar protection of our privacy and security without sacrificing good perte of those functions."
I hope I don't seem too fussy, it just seems to me the most correct way to get privacy and security to a greater number of users.
Regarding Firefox Focus, I think it's a very good idea to include it in PrivacyTools.
Without much more to say, let's continue to help others protect their freedom and privacy. Greetings.
