@Pyrrho @silvermoon82 apparently, Tor will still fail CreepJS if you have JS turned on. it's quite rigorous and i did see a post someone made about a certain extension being the only way they could succeed it, but that extension isn't used by many people so it would be much easier to identify you based on that extension you have installed.
did you take these screenshots or did you find it somewhere else? it doesn't mean much without the proper context. the person using librewolf could just have JS disabled and/or have it very locked down. that will affect web browsing in a lot of use cases, however. i mean, you can't use pleroma without it.
brave is an amazing blend of functionality and security and it's all baked right in to the browser which makes it nice and quick.
it is important to assess your threat level, too. using Tor with JS disabled and in an amnesiac OS is not what most people need. if you're safe enough about what you do on the internet and practice good opsec then you're going to be totally fine.
