wfoex Librewolf is one of the options I proposed that have been frequently proposed in PrivacyTools. It is fine, although personally I would include a reference to the user.js of ArkenFox along with Firefox, for offering more options.
For example, I would put within Librewolf, under the description, the following:
"Another related and similar proposal in practice is the use of the user.js of Arkenfox. This solution could be better for people who have the time and knowledge to choose and edit at the level of code and internal configuration of Firefox the level of privacy and security they want to apply. In any case, and for the average user, Librewolf is the solution."
But hey, if anything, it's pretty good.
To finish polishing the details, Librewolf (as far as I know) is not available for mobile devices, and on the other hand, the DDG browser, although it is promising, I think it is still "too green" to be considered a tool to use to protect your privacy, although I tell you without having tried it, and I have not seen any website where they have put it to the test.
That's it, greetings.
PS: I also think the LibreWolf-ProtonVPN duo is great.
