No. Firefox is not the most secure browser, although it is more amenable to privacy protections. Tor browser is based on Firefox but they are moving to Rust code. Chromium based browsers are supposed to be stronger, but then you’ve got to de-Google it if you want the privacy controls. Brave is good for that.
Libre Wolf is a hardened version of Firefox. No browsers I know of that are commonly used sandbox, containerize, or virtualize by default (like Bromium). So, containerization is a novel and cool feature. Otherwise, you have to use firejail profiles or SELinux. But the other important aspect is shaping the privacy protections of the browser to fit with the site you are interacting with. As most people know, things won’t always work on the net with all protections and security mechanisms in place. So there is a sweet spot that depends on what you are doing. That’s why I think Libre Wolf offers a useful innovation with this feature.
Isn’t this a default feature on Firefox? Is there something special librewolf does with it that I’m not aware of?
